Grade 3-6This epic novel opens with an introductory cartoon strip that tells the top-secret truth about how two kids, George and Harold, used the 3-D Hypno-Ring to hypnotize their principal, who now becomes Captain Underpants whenever he hears fingers snaping. In this second adventure, the boys are banned from attending the annual Invention Convention and sent to detention to keep them out of trouble. This, of course, is impossible, so they sneak into the school that evening and tamper with all of the inventions to wreak havoc. They also make copies of their newest comic strip of vicious attack toilets and the daddy monster of them allTurbo Toilet 2000. The copy machine is an invention that duplicates into live matter all images it copies and the attack toilets come to life. The wild story actually comes to a logical conclusion, but it really doesnt matter. The fun is in the reading, which is full of puns, rhymes, and nonsense along with enough revenge and wish fulfillment for every downtrodden fun-seeking kid who never wanted to read a book. The cartoon drawings and the amazing flip-o-rama pages make this book so appealing that youngsters wont notice that their vocabulary is stretching. Hooray for Captain Underpants!
