Amazon.com Review
The Iron Giant meets Clifford the Big Red Dog in Dav Pilkey's Ricky Ricotta's Giant Robot, the first book in an illustrated series for early readers. Ricky is a young mouse who needs a friend, is bullied by schoolmates, and is waiting for something BIG to happen. But he never expected the arrival of anything as big as Dr. Stinky McNasty's giant robot, created by the evil doctor to destroy all of Squeakyville. When the robot refuses to demolish the town, however, Ricky steps up to save it from the ensuing wrath of the maniacal doctor--twice! In some very Clifford-esque perspectives, the friendly iron giant dwarfs Ricky's neighborhood, scares crows (and bullies), and allows Ricky's new friends to ride on his back. In the end children will be satisfied to see the doctor's secret cave detonated by the very electro-rocket he wanted to use on his errant robot, and even more satisfied to see the robot depositing Dr. Stinky McNasty into the city jail. (Ages 6 and older)
