Chibi-Robo is the main protagonist and namesake of the Chibi-Robo! video game series. It is a four inch-tall robot designed by Citrusoft with the goal to make people happy. Chibi-Robo lives within a house shaped like its head, known as a Chibi-House.
Chibi-Robo's design is bland. Its body is a made of a silver metal, and its limbs short and thin compared to the rest of its body. It has large black eyes on the appendage designed to be its head, and has a flat platform atop, likely acting as a lid for the robot's circuits. Chibi-Robo has a "tail" of sorts, being a black chord that ends with an electrical plug that is used to charge the robot.
