Chibi-Robo!

Chibi-Robo! (Japanese: ちびロボ!) is a series of adventure video games developed by Skip Ltd. and published by Nintendo.

The franchise follows a series of tiny robotic units known as Chibi-Robo, whose purpose is to spread "Happiness". Recurring game elements of the franchise include monitoring Chibi-Robo's battery usage at all times, and cleaning Chibi-Robo's nearby environment through a variety of methods in order to collect "Happy Points", the game's collectible representation of the happiness the players instill in others. While the primary purpose of a Chibi-Robo is to assist humans, they have also been shown to assist animals, sentient alien life, and even living toys.
