This sixth, hilariously snotty installment in the bestselling Captain Underpants series brings back the dynamic duo of fourth-grade pranksters, George Beard and Harold Hutchins, who have to face their most disgusting enemy yet. Their class nemesis, the smug school brainiac Melvin Sneedly, is the target of their latest elaborate prank, but the tables are dramatically turned when Melvin attempts to create a formidable Bionic Booger Boy robot using his own invention, the Patented Turbo-Powered Super-Slimey Reverse-Polarity Battle Suit. A series of unfortunate events, including a massive sneeze, results in Melvin merging with his invention, transforming him into a monstrous, mucous-covered menace. Only Captain Underpants, the dim-witted but incredibly powerful superhero alter ego of their tyrannical principal, Mr. Krupp, can stop this snotty, rampaging disaster. The book is packed with Pilkey’s signature flip-o-rama action, silly humor, and empowering themes of friendship and creativity, even when facing a giant, booger-wielding foe.
