Ricky Ricotta is lucky to have his Mighty Robot as a best friend. They play, study, and even get in trouble together, and they always watch out for each other. That's what friends are for!

When Major Monkey plays a trick on Ricky's Robot, it's up to Ricky to rescue his friend and stop Major Monkey from menacing mousekind!
