School Library Journal Review
Gr 2-4-Pilkey again features the absurd faculty members of Jerome Horwitz Elementary School and introduces a new science teacher when troublemakers George and Harold drive Mr. Fyde into retirement. Professor Pippy P. Poopypants is a great, but frustrated scientist whom no one takes seriously because of his name. He is certain that the "sweet, innocent" children won't laugh at his unusual appellation. Needless to say, they do, and in so doing, incur a wrath that only Captain Underpants can tame. With its bathroom humor, madcap pranks, gross adventures, mini-comic strips, and flip-book pages, this rollicking laugh-out-loud cartoon story is certain to be a hit, especially with reluctant readers.-Sharon McNeil, Los Angeles County Office of Education (c) Copyright 2010.

Horn Book Review
Because of his funny name, Professor Poopypants doesn't get much respect when he begins teaching at Jerome Horwitz Elementary. Provoked by class cut-ups George and Harold, the professor goes mad, inhabits the shell of a giant robot, and shrinks down the school. The plot is more diffuse than in earlier volumes of the series, and the humor sometimes seems a little desperate. From HORN BOOK Fall 2000, (c) Copyright 2010.

Kirkus Review
Once again Captain Underpants, 'faster than a speeding waistband . . . more powerful than boxer shorts,' plunges to the rescue, saving the tushies of everyone in Jerome Horwitz Elementary and the Ohio town beyond from the heinous demands of a deranged science teacher. Unable to get his shrinking and growing machines'or himself'taken seriously because of his name (go figure), inventor Pippy P. Poopypants finally cracks after reading a comic book featuring The Pied Pooper created by school ne'er-do-wells George and Harold. In no time, the Poop's at the helm of a ten-story robot, shrinking the school to coffin size and forcing all to take names like Loopy Pizzapants or Snotty Gorillabreath from a (given in full) set of lists. He's no match, of course, for Captain Underpants, and after a brief (so to speak) tussle animated by the now-familiar flip-o-rama, everyone is restored to original size as the prof is carted off to the pen. Pilkey's (Ricky Ricotta's Giant Robot, 1999, etc.) cartoon illustrations add their usual amount of gravitas (i.e., none), and heaps of clever puns and repartee leaven the potty humor. Another wiener'er, winner. (Fiction. 9-11)
Booklist Review
Gr. 3^-5. You knew he'd be back. Yes, Captain Underpants, aka Mr. Krupp, principal of the Jerome Horwitz Elementary School, has returned, as have his enablers, students George and Harold. The plot? Suffice it to say Underpants must combat a scientific genius named Professor Pippy P. Poopypants. Poopypants goes mad when the students at Horwitz laugh at his name. (When they find out his middle name is Pee-pee, they get downright hysterical, as will readers, no doubt.) Mixed in with the minimal story is Pilkey's comic book^-style artwork; some of the pages even make a "cheesy" flip book to animate the action. Silly, gross-out fun for Captain's legion of fans. --Ilene Cooper
