Ricky Ricotta’s Mighty Robot [EPUB ebook] 

From the creator of CAPTAIN UNDERPANTS, comes an out-of-this-world friendship adventure – now in full colour! Ricky Ricotta is a lonely mouse. Often he finds himself being picked on by bullies at school. He is waiting for his life to change for the better–for something BIG to happen. Meanwhile, Dr. Stinky Mc Nasty is up to no good. He wants to take over the entire city of Squeakyville. He has built a monstrously-sized robot and now orders it to destroy the city! But with Ricky Ricotta’s help, the robot gets away! Soon, nobody can pick on Ricky Ricotta any more. He and his robot get to teach those bullies a lesson. But Dr. Stinky wants revenge and creates a giant lizard to destroy it. A battle ensues, and in tried-and-true Flip-O-Rama fashion fun, the good guys come out on top!
