Mr. Prongs
Mr. Prongs is a character in Chibi-Robo! who has a plug for a head. To find him, use the Chibi-Radar while on the floor in the Living Room. If it points straight downward, stop, and hit the floor with the Spoon. Than he will appear. Keep doing it and he will dance and grow larger. After a while, he will give Chibi-Robo Happy Points and disappear. Than Chibi-Robo will recieve the Mr. Prongs Sticker. Telly Vision, freaked out that he had a plug for a head, decided to give him a name. It was Mr. Prongs. It is unsure whether Mr. Prongs is considered a toy or something else.
