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.

Fulfilling his duty is his primary goal, though there are various other things he is capable of doing, such as using an internet search engine and claiming that it's an internal database that Chibi-Robo can use.
