If any Psymonster has ever been sure that some Psymonsters were quietly following any Psymonster and making silly faces, but none of the Psymonsters were there when any Psymonster turned around, it was probably Centipedium. He shows up in public parks, outside restaurants, and in market squares anyplace in the Psymonster World, where he performs routines and does an impression of watchers without ever making a sound. Any Psymonsters will not pretend to be trapped in an invisible box or walking against the wind as well as Centipedium does. He has a mischievous and playful Psymonster arround, and the two frequently join forces to get even bigger laughs and applause from their audience.
He is a green magic centipede with teal eyes, eight red arms, a blue shirt with eight sleeves, maroon antennas, eight white gloves, and black shoes.
- Centipedium is the only Bug Psymonster with a shirt.
