Kid Eggplant is a eggplant like character who was in a treasure chest up the tree in the backyard where a digging spot is. After he is rescued he rewards Chibi-Robo by turning him into a eggplant, but Chibi-Robo doesn't like it and wants to be turned back into a robot. He gives Chibi-Robo a Super Eggplant that must be given to the Blue Bird. After this he leaves and isn't seen again. He strongly resembles a character from Wrecking Crew called Eggplant Man.
