The ninth epic English novel by Dav Pilkey!

A highly enjoyable picture novel  - brilliant for reluctant readers! The simple black-and-white illustrations on every page furnish comic-strip appeal. Includes several pages of flip-o-ramas that animate the action. 

In this ninth epic novel, Dav Pilkey takes readers back in time to the carefree days of kindergarten, when the worst thing George and Harold had to face was NOT evil mad scientists or alien cafeteria ladies but a sixth-grade bully named Kipper Krupp, the nephew of their clueless school principal. And because George and Harold don't actually invent Captain Underpants until fourth grade, the two clever kindergartners are on their own -- using their brains to beat the bully.
