The FC Caverns (FCバグステージ, FC Bug Stage) are an area accessible from the hidden passageway of the Techno Condominium.

Features

The FC Caverns is an extremely unique area among all of the worlds in this game, as it does not play out like a typical exploration-based RPG, but rather more like a movement-heavy platformer, akin to Super Mario World.

The world's aesthetic is very similar to that of the Alien Cellar, complete with the color scheme and the strange machines, but considerably glitched-up and distorted. Strange blue tears are visible in the stones of the ground, and the world is overlayed by a sweeping scanline effect along with a staticy humming. Occasionally, the cute sound effects of Urotsuki's jump will glitch out, being replaced with glitchy sound effects.

The area is split up into two separate sections. The first one is a linear platformer to the left, though there's a bit more exploration to be had: by using the Penguin and Fairy effects in tandem, the player can dive under the water here and explore the underwater caves. The second, accessible from a door in the first, is an area where Urotsuki climbs vertically, looping around the screen. Climbing to the very top will lead to a door to the Flooded Dungeon.

Effect

Almost all the effects have a different behavior in this area. While some allow Urotsuki to interact with the world in particular ways, others are purely decorative.

Effects with special interactions

Effect	Sprite	Interaction
Bike		Allows Urotsuki to move faster, but jumps slightly lower than with other effects.
Fairy		Allows Urotsuki to float in water and to slowly elevate when in water. It also allows to fly outside of the water by repeatedly pressing the interaction key, and in addition allows Urotsuki to fit through spaces that are only one block tall.
Twintails		Allows Urotsuki to jump against walls by holding the interaction key, along the key corresponding to the direction of the wall.
Spacesuit		Can slowly float when in water and outside water by holding the interaction key.
Eyeball Bomb		Allows Urotsuki to return to the Nexus by holding the interaction Key. It can't be activated in water.
Maiko		Jumps lower.
Penguin		Allows Urotsuki to swim.
Spring		Allows Urotsuki to jump repeatedly by holding the interaction key, with every jump being higher than the last.
Stretch		Allows Urotsuki to stretch while holding the interaction key. When released, Urotsuki makes a small jump.
Haniwa		Allows Urotsuki to quickly sink in water, but it moves slowly and jumps really low.
Child		Jumps lower. Just like the Fairy, can fit through one-block holes.
Polygon		Allows Urotsuki to create a platform by pressing the interaction key while jumping. Doing it again destroys the platform.
Teru Teru Bozu		Makes it rain.
Bat		Allows Urotsuki to fly by holding the interaction key and pressing the direction keys.
Insect		Allows Urotsuki to get stuck in some walls by holding the interaction key, along the key corresponding to the direction of the wall. Urotsuki jumps when the keys are released.
Drum		Allows Urotsuki to float in water.
Bunny Ears		Allows Urotsuki to jump higher and fall slowly.
Cake		Urotsuki can smash the cake by hitting a ceiling.
Haniwa + Cake		Allows Urotsuki to quickly sink in water, but it moves slowly and jumps really low. Urotsuki is stuck looking to one side.
Bike + Wolf		Allows Urotsuki to move faster, but jumps slightly lower than with other effects.
Red Riding Hood + Teru Teru Bozu		Makes it rain.

  This room looks impossible to navigate without flying effects, and it would be if you couldn't loop around the screen.

• 

  Diving deep underwater.

  I guess this is where the caves just... break. You can't go any further here.

Trivia

The one other NPC in this area, shown in the first image of the gallery, appears to be a reference to VVVVVV, a platformer with a similar aesthetic to this area.
