"Ricky Ricotta's Mighty Robot vs. the Uranium Unicorns from Uranus" (2005) is a children's novel by written Dav Pilkey and illustrated by Martin Ontiveros, the seventh in the series of books.

Plot

The book starts with Ricky being humiliated by his giant robot saying the lines "This is fun! This is NOT fun". Ricky wished that his Mighty Robot would have someone to play with himself, however, Ricky's wish was actually a plan of the evil Uncle Unicorn, who had destroyed Uranus by having previous villains dump waist. He creates a Ladybot, certain that he will be the first one to succeed. Hopefully, he does, and Ricky's robot, hypnotized, falls in love with the Ladybot and gets abducted, unknown to Ricky, who now regrets his wish. Finally, he decides to find his robot and does so in the woods, where his robot is guarded by Uncle Unicorn's Uranium Unicorns, who were under the command of the Ladybot besides the evil Uncle. Ricky, shocked, stops by his cousin Lucy's house to borrow her jurassic jackrabbit Waffles along with Lucy herself. However, upon entering the Ladybot caused them to be captured by Uncle Unicorn and tied up hanging above the Generator.

Ricky discovers that the Generator is sensitive to water and tries to sweat more and spit. He asks Lucy to spit for him, but she refused. Ricky thinks up a plan and makes her burst into tears by saying that everything she loves will be destroyed. The robot breaks free of the spell and battles the Unicorns. However, Uncle Unicorn started the backup generator and grew the Ladybot into a more deadlier machine...who trips from her tied shoelaces. The characters discovers that the cause was made by none other than Fudgie and Cupcake, two other jurassic jackrabbits. Ricky's robot throws the Ladybot and the Uranium Unicorns into space and put Uncle Unicorn in jail ("Hey! This place is getting crowded!"). The book ends with Ricky reading a bedtime story to his Robot.
