Kiwi is a furry stop motion pink monster that sometimes appears and says something random, then waves his arms around, except when Chowder sees himself as bones in the basement and Kiwi says "You can do it Chowder." He is usually seen on a green background with three flies flying around him and only his head is visible, except on the episode "Brain Grub" where you see his body fully and he is on a background of a car shop. The only time anyone ever mentioned his name in the show was in The Brain Grub. He is voiced by C.H. Greenblatt.
Kiwi doesn't have much of a personality. He is usually seen either making fun of the other characters or other things.
He often talks to Chowder, telling him obvious things like, "That's some good thinking, Chowder."
It is possible if he has feelings for Schnitzel; in "Schnitzel Quits" he offers to give Schnitzel his heart forever.
