Snagger

**Snaggers** are unique enemies that will prioritize any pickups in the room, using them against Isaac. If no pickups are left, they will slowly float after Isaac.

## Attacks

### Hearts

* Snaggers will receive a health boost when picking up any heart, shown by gaining a red tint.

### Coins

* Snagger will eat multiple coins if they are close together before spitting them out at Isaac, with each coin adding to the shot's spread. The maximum shot number at one time is 5, the leftover coins being fired shortly afterwards.
	+ Double Pennies, Nickels and Dimes will be worth 2, 5 and 10 coins respectively.
* Snaggers cannot pick up Sticky Nickels normally, but will use bombs to blow them up.
* Snaggers have exceptionally poor gambling skill and will explode if eating Cursed Pennies.

### Keys

* Snaggers will throw Keys at Isaac, which fracture outwards into a V shape upon hitting anything.
* Golden Keys will have them firing 4 times in quick succession.
* Key Rings will let them throw 2 keys at once, in a v shape.
* Charged Keys will have drastically increased shot speed.
* Aware of Fiend's tricks, they will not pick up Spicy Keys.

### Bombs

* Snaggers will lob bombs over towards Isaac, though they will keep their distance from lit ones.
	+ If bombable objects exist in the room such as Stone Chests or Slot Machines, they will bomb them first.
* Double Bombs will have them firing 2 bombs at once in a v shape.
* Golden Bombs will let them throw 4 bombs in quick succession.

### Miscellaneous

* Lil' Batteries will give them a drastic speed boost for a short duration, speeding up even their animations.
* Snaggers will open chests as usual, using Bombs for Stone Chests or Keys for Locked or Eternal Chests.
	+ Snaggers will take damage when opening Spiked Chests, but can open inactive Mimic Chests for free.
* Sacks and Blood Sacks will spill their contents as usual. Trash Bags will spawn a couple enemy flies and spiders instead.
* Snaggers will open Store Chests with Keys, and then take what they can from the store's stock.
* As a self proclaimed winner, Snagger will not touch any pills. Cards as well.

Devil's Umbrella

## Effect

* **Devil's Umbrella** grants half of a Soul Heart upon pickup.
* Every time player shoots a tear, he has a 20% chance to fire a volley of yellow projectiles that leave small puddles of yellow creep.
	+ Tears in the volley deal randomly 0.3, 0.4, 0.5 or 0.6 damage and the creep deals 12% of Isaac's Damage per tick.
	+ Tears in the volley do not scale with player's Damage, Range or Shot Speed.
* The chance to fire the volley does not scale with Luck and will always be 20%.
* Getting multiple copies of Devil's Umbrella will grant half of a Soul Heart every time a copy is collected but other effects will not be affected.
* Volley will not appear at all if tears are replaced with other type of attack, such as Mom's Knife or Brimstone.
	+ This means Devil's Umbrella has no effect while playing Azazel or The Forgotten (in skeleton form).

## Interactions

* Lost Cork: Creep left by tears in the volley will be twice as large.
* Any item that increases amount of tears shot at once: Multiple volleys may occur at once.

Spare Ribs

## Effect

* **Spare Ribs** grant an empty Bone Heart upon pickup.
* Each time player takes damage, a set of 6 rib projectiles will be released from their body and will attempt to come back shortly after.
* The ribs will deal contact damage to all enemies on their path until they return to Isaac's body.
* If the player is standing still, the ribs will directily come back to Isaac the same way they were released.
	+ If player starts moving, however, the ribs will start to orbit Isaac, attempting to return.
* The effect will trigger only if there are no ribs on screen, meaning it won't activate if at least 1 rib is on the screen.
* Ribs will destroy any enemy projectiles on their path, without getting destroyed themselves.
* Each rib will deal its damage only once to each enemy, no matter how many times the rib and the enemy touch each other, making keeping the ribs on screen too long pointless.
* Rib damage is equal to player's damage.
* Getting multiple copies of Spare Ribs will add an empty Bone Heart every time the item is picked up and the amount of released rib projectiles will be increased by 6 for each copy collected.
* The effect cannot be triggered while being invincible.

Boom Flies

Boom Flies are characterized by bouncing diagonally around the room and releasing an explosive attack when they die.

## Fossilized Boom Fly

### Entity ID

960.680

**Fossilized Boom Flies** drop to the ground upon death in the form of a stationary boulder with 20 HP, which deals no contact damage but explodes into a shower of rock projectiles after being destroyed. The boulders spawned by Fossilized Boom Flies do not need to be killed to clear a room.

Fossilized Boom Flies will also create rock bridges if destroyed over a one tile wide pit.

## Warhead

### Entity ID

25.962

**Warhead** explodes into eight yellow projectiles and leaves a large puddle of yellow damaging creep upon death. Warheads also fly noticeably slower than normal Boom Flies.

## Doom Fly

### Entity ID

25.960

When **Doom Fly** dies, it releases six boomerang rib projectiles which travel outwards and then converge at the point where the Doom Fly died.

## Trickle

### Entity ID

960.682

**Trickle** bounces around the room like a normal Boom Fly at first, but after taking 10 damage it will fall to the ground and turn into a spider-like enemy. In its spider form, it will quickly skitter towards the player and occasionally hop to release a ring of eight blood projectiles. Upon dying in either form, it will release a ring of twelve blood projectiles.

Mistmonger

**Mistmongers** are unique ghosts that serve only as a visual distraction. A few seconds after entering the room, a Mistmonger will open its mouth and charge out of the room. Shortly after, dozens of translucent Mistmongers will charge in from the right wall and obscure the screen with the real Mistmonger drifting in moments after.

## Gallery

Guflush

**Guflushes** slowly walk towards Isaac, constantly spewing tears out of the top of its head. The tears are very short range and are not the greatest threat to Isaac.

Occasionally, the Guflush will begin inflating a Tar Bubble on top of its head. With a Tar Bubble active, the Guflush will not spew out tears. Once inflated with tears, the Tar Bubble will pop when the Guflush is damaged and shower the area with tears. If the Guflush is left alone with an inflate bubble, it will pop it itself after a short duration. Bubbles popped this way will fire more tears and leave a puddle of black creep.

## Gallery

Nugget Bombs

## Effect

* **Nugget Bombs** grant 5 bombs upon pickup.
* All of Isaac's bombs will spawn a stationary, friendly fly turret that automatically shoots tears at nearby enemies.
	+ The fly turret resembles that one spawned from Brown Nugget.
	+ The flies are invulnerable and deal no contact damage but their tears deal 2 damage.
	+ All flies will despawn upon leaving the room.
	+ A turret's damage, range and fire rate do not scale with player's stats.
* Getting multiple copies of this item will grant 5 bombs every time it is picked up but no additional flies will spawn from bombs nor turret damage will increase.
* The turrets share their limit with Blue Flies and Spiders, meaning you can't spawn any if you have 64 Blue Flies/Spiders.

## Synergies

* Dr. Fetus: Bombs fired by the player will spawn fly turrets.
* Mr. Mega: Damage of the turrets is increased to 3.2 per tear.
* Bob's Curse: Turrets have chance to inflict poison with their tears.
* Hot Bombs: Turrets have chance to shoot Fire Mind tears.
* Sticky Bombs: Turrets have chance to inflict slowness with their tears.
* Butt Bombs: Turrets have chance to daze enemies with their tears.
* Glitter Bombs: Turrets have chance to charm enemies with their tears.
* Bobby-Bomb: Turrets now fire homing shots.
* Scatter Bombs: Small bombs created from the main explosion will create tiny fly turrets whose tears deal 1 damage to enemies.

## Interactions

* BFFS!: The fly turrets appear bigger but their stats are unchanged.
* Box of Friends: Instead of copying the flies, using Box of Friends will delete them all.
* Sacrificial Altar: The turrets can be sacrificed for items from the Devil Room's pool.
* Anarchist Cookbook, No. 2, Explosive Diarrhea, Mr. Boom: Bombs spawned by these items will create fly turrets as well.
	+ Other explosion-creating items, like Kamikaze!, Epic Fetus or Best Friend will not spawn fly turrets.
* Sad Bombs, Fast Bombs: The bombs gain unique appearance but they do not benefit from those items.

Wobbles

**Wobbles** are floating mushroom enemies that make small lunges at Isaac. They are fairly stationary apart from their lunges and even then, their dashes don't travel too far. Occasionally, however, they will inflate while lunging and travel much farther. While inflated, they are affected more strongly by knockback.

## Trivia

* Wobbles is based on a Hollow Knight enemy called Hwurmp.

## Gallery

Head Honcho

**Head Honchos** are large, disembodied heads piloted by a maggot. They alternate between two attack patterns. The first has the maggot fire out 3 bursts of three blood shots in quick succession. Following that attack, the Head Honcho will charge horizontally off screen. It will charge through the room horizontally three times before returning to its normal state. In the middle of each charge, the maggot will fire a burst of 4 shots towards Isaac.

Once the Head Honcho is killed, it will slowly being accelerating towards Isaac while flashing red and bleeding. After a moment, it will explode into a shower of blood shots and a single Charger.
Ramblin' Evil Mushroom

**Ramblin' Evil Mushrooms** walk around the room along a pre-determined path, occasionally stopping to launch a spore into the air. The spore slowly drifts down until it hits the ground, spawning a Shiitake.

## Shiitake

### Entity ID

960.750

**Shiitakes** are tiny, stationary mushrooms. If Isaac gets within a certain distance, it will fire a tiny blood shot at him, and oftentimes multiple of them can be found occupying a single tile.

## Trivia

* Ramblin' Evil Mushroom's name is a reference to the enemy of the same name from EarthBound.
* Shiitake resembles a Puff-Shroom - a plant from Plants vs Zombies.
Squire

**Squires** look like Knights with no armor, leaving its brain exposed from all directions. In return, Squires wield a bone club which it uses to protect itself from the front. Squires pursue Isaac wildly, moving loosely and not limited to the grid like movement of Knights. If a tear is fired at it from its front, it will try to block it with its club. Even piercing or spectral tears can be destroyed by it.

Occasionally, it will swing wildly while charging in a straight line.
Artery

**Arteries** are obstacles found in Utero. They will constantly spawn forth Blood Cells, either grounded or Spinning, which will find their way to a Vein. They will continue spawning them, even if the room is cleared unless a room-clear button was pressed.

Arteries will not spawn Blood Cells if there is no viable path towards a Vein.

## Vein

### Entity ID

960.371

**Spinning Blood Cells** are flying versions of Mobile Blood Cells. They will be able to fly directly to their Veins over rocks and pits, but otherwise act the same.

Warden

The **Warden** is an angelic enemy that patrols the Cathedral.

The Warden has no means of directly damaging the player outside of contact damage but regardless still poses a danger when accompanied with other enemies. This is due to his unique ranged attack where he periodically launches a star-shaped projectile that perfectly tracks the player. If this projectile collides with the player, instead of dealing damage it will trap the player momentarily within a circular spotlight only around 6 1/2 tiles wide while the rest of the room goes dark. The edges of this spotlight act as a barrier which only enemies and tears can bypass, rendering the player to a significant disadvantage due to the greatly restricted movement space.

All Wardens will cease firing further projectiles while the player is trapped within the spotlight.

## Trivia

* The Warden bares a resemblance to the player's appearance during the Guardian challenge, with a blindfold, flight and long majestic hair.

## Gallery

Globulon

**Globulons** are large spiders that like to be left alone. If Isaac is nearby, they will try to retreat while periodically spitting tiny bubbles at Isaac. When left alone, however, they will try to pump up a bubble 3 stages before launching it towards Isaac. If interrupted while charging up the bubble, it will make a small hop in surprise and toss the bubble as is.

Its charged bubble acts differently from normal bubbles in that they're full of water. Each stage gains an upgraded attack that is released once the bubble is popped. The smallest size fires a single tear at Isaac, the second stage fires a plus. The final and largest stage releases 8 tears in a ring when popped.
Tado Kid

**Tado Kids** follow Isaac, but stay a respective distance away. They occasionally fire a large homing shot at him, which splits apart into a triple shot after travelling a short distance. The large shot homes and deals a full heart of damage, the shots after it splits do neither.
They have a small chance of spawning a Tot upon death.

## Tot

### Entity ID

29.960

**Tots** are headless Tado Kids that act similarly to hoppers. Each time they jump, they lob a homing shot towards Isaac. The shot does not go too far, but it's arcing nature means that it's somewhat easier to be hit by it close range.

## Trivia

* Tado Kids originate from The Legend of Bumbo, another game by Edmund McMillen that takes place within Isaac's story.
Psi Hunter

**Psi Hunters** are demonic enemies armed with a large knife. Psi Hunters pursue Isaac in long and straight charges, making quick turns if Isaac veers too much to the side. When Isaac gets close enough, the Psi Hunter will make a small dash forward and swing its knife from the side.

If the Psi Hunter is close to Psionic enemies, it will target them before Isaac. If the Psi Hunter is surrounded by multiple targets, it may charge up briefly for a spinning attack.

The Psi Hunter has the ability to block Brimstone beams. It will still take damage, but it will generally be reduced and the beam will not travel beyond it.

## Gallery

Poobottle

**Poobottles** have little interest in attacking the player directly, instead opting to target and destroy poops across the room. They normally hover high above the ground and are immune to player attacks, but they will travel over poops and slam into them to spawn eight projectiles in a ring and destroy the poop. After slamming into the poop they will be stunned on the ground and vulnerable to damage. If there are no poops remaining in the room, they will choose to leave it entirely, and the room will be cleared if there are no other enemies left afterwards.

The projectiles created by Poobottles vary depending on the types of poop they destroy. Any items spawned by poops or effects activated upon their destruction will occur as they normally would.

* **Brown**: Brown projectiles
* **Corny**: Brown projectiles
* **Red**: Pink-red projectiles
	+ The red poop does not damage Poobottle and may regenerate to be used by it multiple times
* **Rainbow**: Rainbow projectiles
* **White**: Spectral projectiles
* **Black**: Black projectiles
* **Gold**: Golden projectiles and coin projectiles
	+ Gold poops are durable and may take the Poobottle several attempts to fully destroy
* **Shampoo**: Spawns 4 bubbles in the diagonal directions which linger in the room

## Drainfly

### Entity ID

960.561

**Drainflies** are upgraded versions of Poobottles and behave similarly to them, but after their initial attack of eight projectiles, they will latch onto their poop for a continuous period and spawn many projectiles and/or enemies around itself.

Like Poobottles, Drainflies will have special projectiles for each type of poop, along with other bonus effects. Their initial projectiles will be identical to Poobottles, but their special attack afterwards will much more distinctive.

* **Brown**: Spawns brown projectiles and Dips
* **Corny**: Spawns brown projectiles, Corny Dips, and black Flies
* **Red**: Spawns Spicy Dips and explosive bubbles identical to those spawned by Warty

* **Rainbow**: Spawns random projectiles and enemies from all other poop types
* **White**: Spawns spectral projectiles and Menaces
* **Black**: Spawns a puddle of black creep and Blots
* **Gold**: Spawns numerous coin projectiles
	+ Like with Poobottles, Drainflies can use gold poops multiple times due to their durability
* **Shampoo**: Spawns bubbles and Drips
Mama Pooter

**Mama Pooters** are engorged, stationary Pooters that attack occasionally. If Isaac is below it, the Mama Pooter will fire a large tear at him which leaves a trail of creep. Upon impact, the tear will pop into a small flurry of smaller tears which do not leave creep. If Isaac is elsewhere, the Mama Pooter will spawn a Creepy Maggot instead with a maximum of two out.

On death, the Mama Pooter will spawn an assortment of enemies:

* One Creepy Maggot
* Two Pooters or Super Pooters
* Two Black or Attack Flies

Kingpin

**Kingpin** is a large, segmented worm boss who is found in Chapter 2.

## Behavior

* Kingpin spends most of the fight burrowing in and out of the ground like a giant version of Weaver, constantly chasing the player.
* When one of Kingpin's segments is destroyed, it will release a burst of three evenly-spaced tears in random directions.
* Kingpin can divide and split into multiple smaller worms as his segments break, similarly to Larry Jr.
	+ Kingpins with a large amount of segments can have multiple parts of their body within and outside of the ground at once.
	+ Kingpin moves faster the less segments it has.
	+ A Kingpin worm needs a minimum of two segments in order to stay alive.
* Occasionally, Kingpin's head will slide along the ground and several single blood projectiles towards Isaac while it slowly moves towards him.

## Trivia

Spinneretch

**Spinneretches** slowly hop through the room, occasionally choosing one of two attacks. One attack has the Spinneretch spewing out small tears at Isaac for a short duration, with a short range and tracking Isaac while firing. The other spawns a single Spider Egg.

## Spider Egg

### Entity ID

950.0

**Spider Eggs** are stationary enemies that passively leave a puddle of white creep. They have two effects on death, depending on how they were killed. If killed normally, they will spawn a swarm of Baby Spiders. If stepped on, they will create an x or + of white creep.
Cursed Penny

Cursed Pennies are a new variant of coin pickups that can sometimes be found in specific room layouts. They can also replace other coins or drop as a room reward if player holds Fool's Gold.

A Cursed Penny has a random value between -2 and 2. Sometimes it can also cause a variety of effects that depend on the generated value:

* On -1, an explosion can occur, damaging the player.
* On -2, a green fart cloud may be created, poisoning nearby enemies.
* On 1, the penny may increase player's Luck by 1.
	+ Very rarely, player can get a very minor *all stats up* instead.

## Trivia

* Cursed Pennies originally were a part of Devil's Harvest mod.
* Coincidentally, in Repentance, an actual trinket named "Cursed Penny" was added. The trinket has no relations to the Fiend Folio pickup, however.
Splattercap

**Splattercaps** are large mushrooms that do nothing without a Cordy. If a Cordy is in the room, they will jump on top of Splattercaps periodically, splashing a large amount of red tears nearby. If Splattercaps are the only enemies in the room, they will explode into a damaging fart.

## Cordy

### Entity ID

960.2001

**Cordies** are fungal Hoppers that work in tandem with Splattercaps. If there are Splattercaps in the room with them, they will jump high into the air and land on a Splattercap to trigger its attack. They may switch Splattercaps while in the air. If no Splattercaps exist, they will jump aggressively after Isaac.

## Trivia

* Splattercap's appearance is based off of the Bleeding Tooth Fungus, known for its unique appearance.
* Splattercap is a returning enemy from Devil's Harvest, originally being named Fatshroom.

## Gallery

Dweller

**Dwellers** are enemy versions of Isaac, moving and shooting in a similar way, and even using items in the same way.

The kinds of items Dwellers can use and how they affect them are as follows:

* **Inner Eye**: This makes the Dweller shoot 3 tears at once, at a slower rate.
* **Spoon Bender**: This makes the Dweller's tears homing.
* **Number One**: This gives the Dweller fast-firing tears with a very short range.
* **Brother Bobby**: This will spawn a Dweller Baby to accompany the Dweller.
* **Technology**: This replaces the tears with a laser that has a slight tell before firing.
* **Polyphemus**: This gives Dwellers a large, slow-firing tear that deals double damage.
* **Cricket's Body**: This will make the Dweller's tears split into 4 smaller shots upon colliding with the ground, walls, rocks or the player.
* **Cursed Eye**: This will give the Dweller a charge attack that shoots 4 tears in a line.
* **Soy Milk**: This will give Dwellers very small tears and a very high fire-rate, even faster than Number One.

## Dweller Baby

### Entity ID

960.81

Dweller Babies accompany Dwellers when they use Brother Bobby. They will follow Dwellers who spawned them and will fire blood shots alongside them.

## Trivia

Red Ribbon

## Effect

* **Red Ribbon** will transform all Eternal Heart pickups into Full Eternal Hearts.
	+ Full Eternal Hearts will instantly grant a filled heart container without needing to find another Eternal Heart or travelling to the next floor.

Sticky Sack

**Sticky Sacks** are a much more fragile version of Sacks, having less than half their health. This means that they will both die quicker and heal back to full health quicker than normal Sacks.

They also spawn a small swarm of Baby Spiders on death.

## Walking Sticky Sack

Monsoon

**Monsoon** is an aquatic version of Monstro, and is found exclusively in the Flooded Caves.

## Behavior

Monsoon will always start off the battle in his smaller form, before quickly melting into the ground and dropping from the ceiling in his full-size form.

While not attacking, Monsoon may hop towards the player like how Monstro does, but covering more ground with each hop in comparison. He has a wide variety of attacks he can use which are as follows:

* Monsoon spits out a large cluster of tears at the player, similar to Monstro's blood vomit attack but larger and quicker.
* Monsoon will summon several bubbles across the whole room, of varying sizes.
* Monsoon spits out a large tear into the sky which slightly homes towards Isaac and rains down a shower of tears alongside 2 Drips.
* Monsoon melts into the ground and then drops onto Isaac's location 3-5 times in a row, scattering a ring of eight tears each time he splashes into the floor.
	+ When he drops from the ceiling for the last time he scatters a larger, randomized ring of tears.
* Monsoon may inflate himself to larger size and move to the center of the room. Once there, he will release large amounts of tears in random directions while slowly deflating himself.
	+ The rate at which his shoots projectiles increases the smaller he gets, and also release a few projectiles which travel in a circular pattern.
	+ Once he has deflated back to normal size, he releases a ring of sixteen tears and the attack ends.
* Monsoon can choose to turn himself into a smaller form, launching a pair of charging Dribbles in a wide V pattern towards Isaac as he does so. While in his smaller form, he has a limited and altered movepool.
	+ Monsoon can still hop towards the player while smaller, and will additionally spit a small cluster of tears towards Isaac each time he does so.
	+ His other attack while small is his divebombing attack, but he will not create any projectiles when he uses it in his small form.
	+ Eventually, small Monsoon will melt into the ground and drop from the ceiling in his normal-sized form, scattering a ring of tears as he does so.
* Upon death, Monsoon spawns a single Drip.

## Trivia

* There are options in the mod's Dead Sea Scrolls menu to change Monsoon's name.
	+ There are currently four choices: Monsoon, Moistro, Jack the Dripper, or Jack Moistro the Monsoon Dripper.

## Shitling

### Entity ID

960.500

**Shitlings** are primarily spawned by Tall Bois, but can be found on their own as well. They are firmly entrenched within the floor and fire a single poop bullet at Isaac if he is close enough.

## Trivia

* Tall Boi's design originates from The Legend of Bumbo, another game by Edmund McMillen that takes place within Isaac's story. However, Shitlings are original.
Gapers

Gapers are one of the most common enemies of first chapters. They act by usually chasing Isaac in attempt to deal contact damage.

## Morsel

### Entity ID

960.50

**Morsels** are tiny, fragile gapers but are none less threatening. They usually come in small groups, hoping to rush down Isaac before he can quickly dispatch of them.

### Notes

* Morsels created by Mouthfuls have slightly different appearence, resembling scarred Gapers.

## Pester

### Entity ID

960.830

**Pesters** act similarly to Gapers, but come with an Eternal Fly attached. The Eternal Fly will stay attached if the Pester becomes a Pacer or Gusher on death.

## Marge

### Entity ID

666.180

**Marges**, despite their threatening appearance, are only home to a group of Swarm Flies who are spawned on their death.

## Fathead

### Entity ID

666.50

**Fatheads** pursue Isaac slowly and explode into a large fart cloud on death. The fart deals no damage, but will knock back both Isaac and other enemies.

## Sourpatch

### Entity ID

960.360

**Sourpatches** act identically to Gapers, but will spawn their head and body on death.

## Sourpatch Head

### Entity ID

29.962

**Sourpatch Heads** act similarly to slower Hoppers, jumping about randomly and pursuing Isaac if he draws near. With each hop, it will also leave a small puddle of damaging lemon creep.

## Sourpatch Body

### Entity ID

960.361

**Sourpatch Bodies** likewise act similarly to Gushers, spraying low range tears in the direction they're moving. However, they fire much more rapidly than normal Gushers. They also move a bit faster.

## Fishface

### Entity ID

960.240

**Fishfaces** follow Isaac normally until he gets too far away. Then, they will dive underwater only to resurface closer by. Groups of Fishfaces will tend to dive at the same time as eachother.
Some Fishfaces wait until the room is cleared to surface for the first time.

## Curdle

### Entity ID

666.140

**Curdles** follow Isaac slowly, leaving behind a trail of creep. A layer of flesh covers their face that will be knocked off upon taking enough damage, spawning 1-2 Leper Flesh and turning the Curdle into a Naked Curdle.

## Naked Curdle

### Entity ID

666.141

**Naked Curdles** move faster without their flesh covering weighing them down. Their unobstructed face also allows them to occasionally fire large, arced tears that pop into a small shower of smaller tears upon impact.

## Trivia

* Marge is a reference to Marge Simpson and her signature hair, resembling the aptly named beehive hairstyle.
* There is a very small chance for a Morsel with a cube-shaped head to appear.
* Warheads and Sourpatches are named after each respective brand of sour candy.
* In the files, in Curdle's folder, a set of various heads can be found. Presumably, they're placeholder sprites or were used in early versions of Curdle.

Gravedigger

**Gravedigger** is a dangerous mini-boss found in the Cathedral. While any other enemies are alive in the room, she will bounce around the room diagonally with a barrier that grants her invulnerability. Once all other enemies in the room are killed, she will remove the barrier and perform one of two attacks.

* Travels to the center of the room and then unleashes three green lines of fire from her lantern which rotate around herself.
* Sends a green spirit out of her lantern to charge across the screen and then reappear from the other side. The green spirit shoots four lasers in the diagonal directions shortly after being spawned, and then another laser before traveling back into Gravedigger's lantern. While the spirit is out, Gravedigger will shovel up a spread of three large spectral tears towards Isaac, twice.

After finishing her attack, she will spawn ghostly enemies and then and grant herself a new barrier until the spawned enemies are killed, which repeats the cycle anew until Gravedigger is killed.

The enemies Gravedigger can directly spawn are as follows:

* 2-3 Yawners
* 2-3 Menaces
* 2 Lil' Haunts
* Peek-A-Boo

## Trivia

* If she is killed while her green spirit is outside of its lantern, the lantern will be left on the floor after she dies. Otherwise, the lantern shatters upon her death.

Craterface

**Craterfaces** are tough, floating enemies with a large growth on their head. Occasionally, it will begin creating a stream of blood shots that begin rotating in a tight circle around the Craterface. Once a full circle is formed, it will fire them all outwards at once. The blood shots will continue rotating while travelling and move at a very fast speed.

If the Craterface dies while attacking, its circle will fire out unfinished after a short delay.
Lil' Jon

**Lil' Jons** are giant Death's Heads that bounce diagonally around the room. They are a fair bit slower than normal Death's Heads and die upon the room's clear as normal.
Unlike normal Death's Heads, they collide physically with Isaac and can block his movement.

## Elite Jon

### Entity ID

960.190.1

**Elite Jon** is a unique Lil' Jon that only shows up on The Real Jon Challenge. The Elite Jon acts the same as Lil' Jons, but will follow Isaac through every room as well as not dying if there are no other enemies.

#### Notes

* Elite Jon can be killed by effects like Chaos Card or Euthanasia, but will reappear in the next room.
Tap

**Taps** will poke out of pots before spilling red creep in a small circle around it. It then retreats to appear in another pot. While normally invincible, they can be killed by destroying the pot they're positioned over. However, this is optional as Taps will deactivate once the room is cleared. As Taps can only exist within pots, they're naturally only found in the Basement and its alts.

## Trivia

* A secret option exists, which causes Taps to create yellow creep instead of red, while sound from a popular meme "Mario Pissing" plays.
Calzone

**Calzone** is a maggot filled monster found in Necropolis. They bound around the room periodically in small leaps and occasionally spawn a random Maggot enemy around them. The potential maggot spawn include:

* Maggots
* Chargers
* Spittys
* Creepy Maggots
* Dank Chargers (Although only when encountered in Dank Depths)

Upon death, the remaining Maggots within burst out, the list above applies to these Maggots too.

## Panini

### Entity ID

666.150.1

**Paninis** are a smaller variant of the Calzone encountered slightly earlier in the Flooded Caves. While Calzone spits out a diverse collection of Maggot variants, the Panini exclusively spawns Drowned Maggots. This also applies to those they spawn on death.

## Trivia

* Calzone (and Panini by extension) were a part of Fiend's Community Poll on Twitter, which would decide which of three enemies would remain in the game as a parody of Minecraft's mob polls. Fumegeist triumphed over Calzone and Dogmeat, who can be removed from the game in one of the mod's settings.

Woodburner

The **Woodburner** is a dangerous foe that appears in the Burning Basement. Normally it paces around the room, but will occasionally decide to start spinning its wooden plank.

Creepterum

**Creepterum** is a bisected corpse, infested with flies and spiders. It is held aloft by three eternal flies that drag it around the room in a diagonally bouncing pattern. Creepterums are all about spawning flies and spiders. Its main attack spawns 2-3 flies or spiders, followed by 3 more flies or spiders released over time. These spawns can either be in groups of flies/spiders, or mixed in with each other.

Once killed, the Creepterum will flop down onto the ground. Every couple of seconds, it will spawn 3-4 flies or spiders and a single Eternal Fly. Once three Eternal Flies are spawned, they will lift it back up into the air where the process repeats.

Once all other enemies (this includes its flies and spiders) are killed, the Creepterum will die.

960.581

**Gravins** are tiny gravestones that only serve to get in Isaac's way. When killed, it fires four low range rocks in the cardinal directions.

Gravins do not deal contact damage.

	+ Brick (Block Gravin)
	+ Lester (Thin Gravin)

The Real Jon

## Goal

**The Real Jon** is one of the three challenges added by the Fiend Folio mod. In this challenge, you start as Isaac with no items. The goal is to defeat Mom's Heart/It Lives.

In the beginning, in the starting room, Elite Jon spawns and follows you for the rest of the run.

Main article: Lil' Jon § Elite Jon

## Difficulty

* Elite Jon can cause some difficulty, as it creates an additional hazard to avoid, while its large hitbox can block player's tears.
* It is advised to keep an eye on Elite Jon to avoid being cornered between him, and a wall or other enemies.
* Narrow corridors and closets are especially dangerous, causing Elite Jon to bounce against the walls more often.
* Enemies can hide behind Elite Jon, while they're still able to fire projectiles, possibly catching the player off-guard.

## Strategy

* Piercing can greatly help, because it will allow tears to pass through Elite Jon.
* Little Horn, Euthanasia or Chaos Card can kill Elite Jon but he will respawn when moving to the next room.
	+ If the player has obtained both Blank Card and Chaos Card, he can save the charge for more difficult rooms to temporarily disable Elite Jon, making the fight easier.
Technopin

**Technopin** is a champion version of the boss, Pin, that appears with Fiend Folio. It appears as a purple version of Pin, with a more stern expression, and a high-tech implant in its face.

## Behavior

* When it jumps out of the ground towards Isaac, it leaves four projectiles which shoot Technology lasers in the diagonal directions after a brief delay.
* When it emerges from the ground upright, it fires a Technology laser directly towards Isaac, albeit with highly delayed tracking.

## Trivia

* Technopin is based off of the boss of the same name from the Devil's Harvest MOD.
