Keystone Cove

**!Spoiler Warning!**: **Plot and/or crucial story details follow.**

## Appearance

Above lies mounds of blue sands. These mounds erupting in boiling, smoking goo. This goo vapor cools the atmosphere above, resulting in the precipitation to come down as frozen water droplets. As this cool air sweeps through these mounds, one of the many openings to the Lunar Temple hides in-between the mounds. This entrance is covered in deadly Snail Spines. The Lunar Temple glows of cyan blue, radiating off of glowing crystals embedded in the walls. The interior atmosphere of the Lunar Temple is quite empty, apart from the black vines and bushes twisting throughout. Though, luminescence reflects off of the shallow water that coats the floor of the temple's halls. An opening on the floor opens up to a spacious aquifer hidden underneath the temple, so open that shoals of Nautilus and even Deep Sea Fish can be seen stalking in the eerie ambience. This cave is almost like a pocketed deep ocean, continued to be lit up by the cyan crystals that occasionally break off and plunge to the bottom.

## Solution

The player will first start above the Lunar Temple, on a small rope of Slime Goo on the ledge. The player will rope down until they stick to one of the sticky blobs of goo on the side of the temple's entrance, and then use their only Common Goo, alongside another Slime Goo ball, to reach the other side of the gap and stick onto the other sticky surface. The player will continue to use Slime Goos to climb up the mound, and detach a small structure on the other side to slide down and awaken the first Keystone Goo.

From there, the player will begin to trek down into the entrance, evading Snail Spines by using the same method to switch from side to side. The player will be met with two small gears on either side. Using the Common Goo ball to hover above the direct gap and droop down using Slime Goos. If done correctly, the detached Slime Goo structure will land on the Keystone Infuser below. The Slime Goo structure should be hooked onto the rightmost gap inside the infuser, and then use the two discovered Keystone Goos on the leftmost and middle gaps. Another separate structure needs to be in-between the keystone infuser and the wall indicated with an arrow pointing downwards.

Back to the right again, the Slime Goo structure that is hooked onto the infuser needs to descend into the hole leading to the underwater section of the level. There are four Jelly Predators orbiting a deadly gear. The Slime Goos need to stick onto one of the bells of a Jelly Predator, who will carry the Slime Goos around the gear until they reach the bottom of the orbit. Detach the Slime Goo from the Jelly Predator so that they slide down the ramp and awaken sleeping Squid Goos. Quickly, attach a Squid Goo to the Slime Goo structure so they float upwards, evading the incoming Basilisk charging from the left side. This will also direct them towards the third sleeping Keystone Goo, which can be used to complete the keystone infuser and open the passage that was previously blocked. Uncovering Fuselayered Goos and Goo Product, use the Fuselayered Goo balls to build to the right of the infuser where the Filter Pipe is located. If the player successfully collects four Goo Product, the level will be completed.

## OCD Solution

To achieve OCD for Keystone Cove, the player must complete the level by collecting 10 gooballs. This one can be done by using the normal strategy with a slight detour. In the underwater section, there is a sleeping Slime structure over on the left side which also contains 2 extra sleeping Goo Product. Right after the player activates the Basilisk, they can then use the Squid Goo to get a Slime structure over to the left side. The player can then wake the sleeping gooballs and attach to the structure using the Common gooball. Once they have the Goo Product, they can then detach and fly the structure back up to the opening. The player must be very cautious of the gear and jellyfish while doing so. If done correctly, the player can then build to the pipe with the extra Goo Product in hand and achieve the OCD.

## Story

Behold, Lunalia's greatest intrusion, the Lunar Temple! An archeological marvel that is only accessible by night, The Player descends into the depths of the Lunar Temple in hopes of finding a ship part. However, upon plunging further and further into the luminescent halls, an ancient evil is awakened. An enormous crab-like creature called The Snapper begins to rebuild itself after centuries of laying dormant. Upon sensing the presence of The Player's arrival, it calls upon the storms to flood Lunalia's interior in hopes of drowning The Player and The Journalist. The two of them must act quickly before the tides flush them out, and must reach The Snapper in order to put and end to its wrath.

## Dialogue

* The Journalist
	+ *Well what a slippery slope that is! An underground tunnel, obscured by all these smoking pillars of sand! The sun seems to be slowly rising once again, too. Which is exactly why we should go in that tunnel! I swear I'm not a vampire, it's just that the sun gets too hot sometimes. And I am actually allergic to garlic. ... Also, you're not crazy. It is indeed snowing. And I promise it's not petrified goo ball carcasses this time. -The vampiric Journalist*
	+ *What do we have here? Something tells me that those three slots up there are important. But what do we put in them? Whatever it is, you're going to need to look for it. Speaking of which... It may be a little difficult to traverse this area. But never fear! As these predator jellies are flawed. You can actually stick onto the "bell" of them! Not even slime goos will slip off of these sticky losers. And I should probably mention, the "bell" is the top part of the jellyfish. Please do not try to attach onto the tentacles! -The Journalist*
* Professor Smith
	+ *--Lunar Temple Log III-- It truly baffles me how advanced these civilizations were. The Lunar Temple is peculiar in that the entrance only becomes available under the influence of the moon in the sky, during nightfall. It's a magical place, with stunning beauty and treasures far more valuable than anything you could think of! These mysterious crystals light up all the pathways and passages, so there is no need to bring a source of light for your travels. But beware upon your exploration, as there is an ancient evil lurking these fluorescent halls... Some of the others say that it is a protector, but I say that is far from the truth. This thing is more likely to be invading Lunalia. It is a dangerous monster that has conquered this place, with the intention of luring trespassers to their doom. An ancient entity brought upon by an equally ancient apocalypse. It would make sense, why these ruins have gone abandoned for so long... ...Though luckily, it appears to have lost one of its limbs. Regardless, I call this divine monster "The Snapper". And it will only continue to grow angrier for as long as we poke around here. It brings upon the storms and floods that have already engulfed this place long ago... -Prof. S*

## Secrets

* One of Professor Smith's articles can be found located in the background, as a silhouette of a signpost. This signpost is difficult to spot, obscured by the darkness in the bottom-left corner of the level's background.

## Trivia

* **Keystone Cove** uses an original soundtrack titled 'Divulgence', composed by Adrian122.
	+ This track is exclusive to **Keystone Cove**.
	+ This track is also heavily inspired by the soundtrack for Celeste, called 'Resurrections' composed by Lena Raine.
* The Journalist's remarks about light and garlic and its relevance to vampires is based on vampire folklore.
* In the background of the underwater section, a sandstone block can be seen. This sandstone block is unique in that its drawing is replaced with a black void and sharp, needle-like teeth.
* Professor Smith's log provides the first description of The Snapper, before being shown in the cutscene after the level is completed.
