George and Harold's principal, mean old Mr. Krupp, doesn't like the pair's pranks or their comic books. And he's cooked up a plan to catch George and Harold and stop their shenanigans â€” once and for all! Here's the story of what happened when that plan back-fired, and Captain Underpants leaped off the page to save the day!
Awesome lenticular cover. Includes a bonus CD w/ Captain Underpants songs and other top-secret cool stuff!
