Captain Underpants and the big, bad battle of the Bionic Booger Boy Part 2 : the revenge of the ridiculous Robo-Boogers : the seventh epic novel Part 2 :

Gr 3-6-This seventh title in the series is witty, fun, and full of adventure. George and Harold think everything is fine as the Robo-Boogers are jettisoned into space, but alas, a complication has occurred. Mr. Krupp, the principal, and Melvin have had their brains switched by the Combine-O-Tron, and they become known as Kruppy the Kid and Mr. Melvin. The Robo-Boogers miraculously return on a space shuttle as Miss Singerbrains, the school librarian, gets into the action by taking the Purple Potty from the basement of the library and Mr. Melvin turns it into a magical time machine (a whole other story). As Miss Singerbrains and the boys fly with their pet pterosaurs, the youngsters regain control of the Combine-O-Tron and the Forgetchamacallit 2000 and they ultimately restore Mr. Krupp and Melvin to their rightful selves. However, the switch does not restore Captain Underpants's powers. Then, just in the nick of time, George and Harold come through. The Purple Potty time machine, which is not supposed to be used two days in a row, awaits the boys, but they, of course, use it again, so the end of this story is just the beginning of the next adventure of Captain Underpants. With fast-paced action and humorous, kid-friendly artwork, this story is creative, imaginative, and truly boisterous.-JoAnn Jonas, Chula Vista Public Library, San Diego, CA (c) Copyright 2010.

A mishap involving a new-fangled machine and an ill-timed sneeze turn nerdy Melvin Sneedly into the gunky, slimy Bionic Booger Boy. In the second volume, Melvin and Mr. Krupp (a.k.a. Captain Underpants) find themselves trapped in each otherÆs bodies. Those who enjoy gross-out humor (i.e., most boys) will probably be laughing too hard to notice the deficiencies in the rather shapeless plots.
