[[Category:qxy]] The FC Caverns 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. Rarely, going through the doors will lead to a small room where the platforms gradually disappear, where all the screen's edges loop around. Going through the door here leads to whatever room the player is supposed to enter next.

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 interactions

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. The bike does not slow down when not holding inputs once movement is began.
Lantern		The flame inside the lantern gets put out whenever Urotsuki goes underwater.
Fairy		Allows Urotsuki to float on top of 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 and moves slower.
Penguin		Allows Urotsuki to swim. Drifting is also much slippier than default, making Urotsuki behave like they are on ice.
Spring		Allows Urotsuki to jump repeatedly by holding the interaction key, with every jump being higher than the last.
Invisible		Allows Urotsuki to phase through semi-solid platforms. Although such platforms are only featured in the platforming section of Zodiac Fortress which behaves similarly to FC Caverns, you are able to phase through the platforms created by Polygon and Rainbow as well.
Stretch		Allows Urotsuki to stretch while holding the interaction key. When released, Urotsuki makes a small jump. Pressing left or right while stretched will make Urotsuki jump out of it, giving her a boost. May be a reference to the Uproot ability from Super Mario Odyssey.
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.
Tissue		Allows Urotsuki to fall slower underwater.
Polygon		Allows Urotsuki to create a platform by pressing the interaction key while jumping. Doing it again destroys the platform. The platform's width varies depending how fast she is going, faster horizontal speed creates a wider platform. Falls slower while underwater
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. Sticking to walls does not work while underwater, but Urotsuki is able to fall slower.
Drum		Allows Urotsuki to float in water, and ascends much quicker than other effects while in water. Whilst underwater or floating on the surface of it, running into walls will cause Urotsuki to bounce off of them.
Bunny Ears		Allows Urotsuki to jump higher and fall slowly, in a manner reminiscent of the Bunny Mario powerup from the Super Mario Bros series.
Rainbow		Running will create a platform under Urotsuki, which allows her to run in the air. It also makes the water's surface walkable, after Teru Teru Bozu has been used to make it rain. Also causes certain rainbow platforms to appear upon being equipped. Falls slower while underwater.
Cake		Urotsuki can smash the cake by hitting a ceiling.
Grave		Pressing down key allows Urotsuki get to the down section.
Crossing		Causes the flickering tiles to stop changing color, turning them completely red.
Dice		Allows Urotsuki to fit in one block space.
Haniwa + Cake		Behaves identically to Haniwa, except it sinks slowly in water. Urotsuki is stuck looking to one side.
Bike + Wolf		Behaves exactly the same as the Bike effect.
Red Riding Hood + Teru Teru Bozu		Makes it rain.

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.
• Similarly, the red-and-muted-pink colorscheme of the area, as well as the overall glitchy aesthetic and 2-dimensional movement are highly reminiscent of the game Strawberry Cubes.
• The shift menu is automatically activated here, even if you disabled it.
• There is a smaller area which behaves similarly to FC Caverns between the connection to Zodiac Fortress from Monochrome Feudal Japan.

Gallery

• 

  beep boop... fancy meeting you here!!

• 

  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.

• 

  A glitch in the system, I see?
