Captain Underpants and the Big, Bad Battle of the Bionic Booger Boy, Part 2: The Revenge of the Ridiculous Robo-Boogers
Clearly one epic novel could never contain the hugely disgusting tale of the Bionic Booger Boy; it makes perfect sense that his story would spill out into Dav Pilkey's seventh epic novel in theCaptain Underpants series,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 thesixth epic novelwhen 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.
