Pilby is an NPC that can be found in-game and will enter the elevator.  Pilby appears as a white anthropomorphic caterpillar with four arms and a light green, cyan green, and azure coloured abdomen. The two extra arms also extrude from the abdomen. They have pink hair to go along with their azure hat, pink bowtie, and cyan green nose. They are slightly shorter than the average Robloxian. 

Pilby is a gloomy, downtrodden NPC. They constantly look down on themself and are easily frightened by the more high-strung NPCs. They often talk about or make reference to their mother, who is stated to be trapped in another dimension. They have a habit of saying "ough" or ending sentences with a clown-like emoticon (":0(").

Pilby will appear during the WHEEL OF floor. If the spinner lands on any event except for “SPECIAL”, Mach will whistle out to Pilby to enter the elevator.

- I see them as a medium sounding  voice who's always depressed and feeling down, so try to do that! (they also look alot like a clown so bonus points if you can mix a goofy sounding clown voice in with that :) )
