Professor Moshimo's Robot Testing Lab is a defunct promo game made by Cartoon Network and the digital creative agency Ralph. In this game, you need to help Professor Moshimo test his robots by becoming a "Robo-Guardian". Weekly prizes (like posters and toys) are awarded for the Robo Guardians who have interacted the most with their robot, for example making it sleep, talk, dance and roam. The robots appearance alters depending on how regularly the Guardians log into the site and how many users form their testing team (each robot can have multiple Robo-Guardians).
