**Crabulon** is a Pre-Hardmode boss. It has the appearance of a giant, gray, fungus-covered crab, with several glowing mushrooms attached to it.

## Spawn

Crabulon is summoned by using the Decapodita Sprout in a Glowing Mushroom biome.

## Behavior

When spawned, Crabulon will be passive towards the player, completely still and dealing no contact damage. While Crabulon is passive, the player is granted the Mushy buff, increasing defense by 5 and life regen by 1. It will become hostile if the player attacks it.

Once hostile, Crabulon will begin walking around and jumping at the player, all while firing a series of mushroom projectiles. It also starts summoning small Crab Shroom minions, which slowly float downward while drifting towards the player.

Crabulon enrages outside of the Glowing Mushroom biome and on the Surface, increasing its running speed. The enrage is even more effective if both conditions are met.

### Attacks

* Every 5.375 seconds while idling, launches one at the player, which is affected by gravity.
* After 6 seconds of idling, repeatedly slam its claws around. While in this animation, Crabulon jumps towards the player three times each with a five-second delay.
* When 5% of its health is lost, the resulting hit launches 2 / **2-3** / **3** upwards.
	+ Crab Shrooms drift back and forth around the player, and have a constant falling acceleration.

### In Expert Mode

* Gains the ability to leap through solid tiles.
* When below 66% health:
	+ The number of Mushroom Shots increases from one to three
	+ Fires Mushroom Shots 33.33% faster
	+ Increases horizontal and projectile speed
	+ Reduces the delay between jumps by 80%
	+ Jumps four times instead of three
* When below 33% health:
	+ The number of Mushroom Shots increases from three to six
	+ Fires Mushroom Shots 40% faster
	+ Increases horizontal and projectile speed
	+ Reduces the delay between jumps by 40%

### In Revengeance Mode

* Fires a large and random spread of **11** / **15** into the air as Crabulon lands its final jump in each sequence.
	+ While below 66% health it instead fires **20** / **24** Falling Mushrooms every other jump.
* Crabulon's jumps scale in height based on vertical distance to the player and attempts to intercept them if they are moving.
* Each jump varies in length and delay.
	+ The first jump is normal in length and delay.
	+ The second jump is higher and slightly shorter delay.
	+ The third jump is lower and very short delay.
	+ The fourth jump is lower but longer and extremely short delay.
* Crab Shrooms have a 25% higher terminal fall speed.

### In Death Mode

* Idles for less time the lower its health, up to two seconds less.
* Moves faster, and even faster as its health decreases.

### On the For the worthy seed

* Defense increased to 20.
* Moves faster.
* Is 50% larger.
* Crab Shrooms have their health increased to 30 / **60** / **60** / **60**.

## Notes

* If Crabulon is stuck and cannot get to the player, it can swim through blocks, similarly to the Mourning Wood and Everscream.

## Tips

*For more elaborate strategies on defeating Crabulon, including weapon and arena recommendations, see Guide:Crabulon strategies.*
* Stay underground when summoning the boss, as going to the surface will cause Crabulon to enrage, even if the player is in the Glowing Mushroom biome.
* The player should try to stay above Crabulon, as its stomp attacks deal great amounts of damage. However, be wary of Crabulon's other attacks like its exploding mushrooms and Crab Shrooms.
	+ Avoid staying *directly* above Crabulon as many projectiles come from it and go upwards.
* Although Crabulon can be fought as the first boss, be careful as the boss can easily overwhelm an unprepared player.
* In Revengeance and Death Mode, move slowly during Crabulon's falling mushroom wall attack in order to easily dodge them.
	+ This attack always happens on Crabulon's 3rd jump.

## Trivia

* Crabulon's theme is **1NF3$+@+!0N**, which was composed by the artist DM DOKURO.
	+ When 1NF3$+@+!0N is played through a vectorscope, portions of the song create shapes that resemble mushrooms.
	+ The theme's name reads "Infestation".
	+ If the Calamity Music add-on mod is disabled, **Boss 4** will play instead.
* Crabulon can be fought before any boss is defeated, as its summoning item only require Glowing Mushrooms.
* Crabulon is often referred to as "The Perfect One" in the player base in reference to its former lore where it was given the title.
* If the Boss Checklist Mod is installed, its unique despawn message will be "The mycelium crab has lost interest."
