Chet is a character from the Nintendo DS video game Chibi-Robo!: Park Patrol. In the game he is a snake like robot with a spherical head. He is of multiple colors, the primary one being pink, though his head also consists of green, yellow, and blue. Chet is connected to the Chibi-House, much to his disappointment. He had cartridges with him that instructed him on park projects he was required to perform, but unfortunately lost them on the way to his destination. So, with this, he asked his newfound friend Chibi-Robo to traverse the land and find the lost cartridges.
