Flowey

Flowey is a special floor in the Elevator Universe. It consists of a large black arena surrounded on three sides by the signature Photoshop Flowey boss from the game Undertale.

This particular floor is special in a way that it cannot be accessed in public servers without the Custom Floor gamepass, as the game's RNG floor picker skips over this floor. Effectively, this means that accessing this floor is only possible by using Robux to buy the floor gamepass. As a result, the floor level number remains unknown. This is also true for FloodEscapeLEGACY.

Plot
The floor begins by teleporting players to an older version of the game's elevator. Photoshop Flowey will then transition onto his position around the arena in the same way that he does in Undertale. The elevator will then blow apart into pieces, which will fall into the black void under the arena. Flowey will do his signature evil laugh, before slowly moving back and forth while attacking random players for about 1-2 minutes. When the boss fight is over, Flowey will "explode" in the backdrop while the surviving players are teleported back to the main elevator.

Flowey's Attacks
Laser Beam: Photoshop Flowey opens his mouth and shoots a large cyan beam down the center of the arena, reaching far out of the floor's borders. The beam's position will be indicated by a blinking red and yellow indicator, which will last for about 2 seconds before Flowey shoots. The beam deals 15-20 damage on contact.

Fly Swarm: Photoshop Flowey summons a swarm of flies which move slightly faster than the player in randomly placed invisible lines along the arena. Each one deals around 10 damage; hitting multiple flies will rapidly build up damage can can kill players if they are not careful.

Homing Caterpillars: Photoshop Flowey targets a few random players in the arena and shoots streams of fast-moving caterpillars at them; the paths the projectiles will take are indicated by blinking red-yellow lines. They deal ~5 damage each and can rapidly scale damage if more than one caterpillar hits a player. Flowey will often perform this attack multiple times before switching to another one.

Ball Circles: Photoshop Flowey summons 6 blinking circles around random players. 9 small white balls will appear around them in a circular fashion and close to the center of each circle before moving out towards the outer edges of the floor. Touching any of the balls will deal 8-10 damage on contact.

Map Objects
Periodically, small red hearts will appear in random locations around the arena during the boss fight. Picking one of them up will completely heal the player if they took any damage. The hearts will blink and disappear if they are not picked up after a while.

Trivia

 * Unlike some other iterations of this boss in different elevator games, players can jump to avoid Flowey's attacks while in the arena. This is due to the fact that you can morph into a chair and make players sit on you and the players that are sitting on you can not jump.
 * Flowey will stop his attacks when a warning sound plays, similar to the ones used in Undertale when the boss fight transitions into another phase.
 * The Flowey floor can be picked in private servers without using Robux, as the private server owners are automatically given admin commands.
 * The fight can easily be survived if a player uses Forcefield Potions or has enabled Phantom Mode.
 * Flowey currently remains the only "boss fight" in the game.
 * Surviving Flowey awards you 5 Tokens instead of the usual 1.
