Captain Underpants and the Terrifying Return of Tippy Tinkletrousers (Full Colour Edition) (Book 9)

In the ninth epic novel, George and Harold encounter their biggest challenge yet in the form of Tippy Tinkletrousers, who is back for revenge with his time-traveling antics. The two friends, along with Captain Underpants, must face off against Tippy as they navigate through time, experiencing laugh-out-loud adventures and facing the consequences of altering the past. When we last saw our heroes, George and Harold, they were under arrest and headed for prison. Then Harold foolishly uttered the fateful words 'What could be worse than going to jail for the rest of our lives?' and changed the course of human history. 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. Hold on to your UNDERPANTS -- the Captain is back!
