From the creator of CAPTAIN UNDERPANTS, comes an out-of-this-world friendship adventure - now in full colour. Ricky Ricotta and his Mighty Robot are in big trouble. After crashing the Ricotta family mini-van while using it as a skateboard (it`s the only thing big enough for the Robot), they have to earn some money fast to pay for the repairs. While they`re thinking about how on EARTH they`re going to come up with the money, mean Major Monkey is making plans to enslave mousekind! Major Monkey has had his eye on earth for some time now, and he`s noticed that all the evil villains who have tried to conquer the planet keep getting foiled by Ricky Ricotta`s Mighty Robot. So the first thing to do is get rid of that Robot! Major Monkey tricks Ricky`s Robot into going to Mars. Now it`s up to Ricky to rescue his Robot and defeat Major Monkey.
