Captain Underpants and the Big, Bad Battle of the Bionic Booger Boy, Part 2: The Revenge of the Ridiculous Robo-Boogers

It all started in the sixth epic novel when Melvin Sneedly, a nerd, invented a "combine-o-thingy" that morphed Melvin, a robot, and (accidentally) mucus from his sneeze and created the monstrous Bionic Booger Boy. Unfortunately, in the chaos that ensues, the school principal Mr. Krupp's brain switches to Melvin's body and vice versa (making for a very unhappy school secretary). The diabolical Melvin becomes power-hungry when he realizes that he might be able to keep Mr. Krupp's Captain Underpants superpowers for himself! Can George and Harold stop Melvin from tyrannizing the school--and the world--in his new guise as principal and superhero?

Pilkey's heavily illustrated books with comic-book inserts, "flip-o-rama" animation, and loads of gross-out humor are guaranteed to delight elementary-school boys. (Ages 8 and older) --Karin Snelson
