George and Harold’s time-traveling Purple Potty lands them in a crazy place in the eighth book in this #1 New York Times bestselling series by Dav Pilkey, the creator of Dog Man!
The teachers are nice, the cafeteria serves delicious food, and the school principal, Mr. Krupp, thinks George and Harold are hilarious. Something is very, very wrong – and it gets even wronger when the boys’ pet pterodactyl, Crackers, and Sulu the Bionic Hamster are captured by George and Harold’s evil-twin look-alikes. Now George and Harold must face their greatest foes yet: THEMSELVES! Can they handle this mess on their own, or will they need Captain Underpants to swoop in and save the day?
When Dav Pilkey was a kid, he was diagnosed with ADHD and dyslexia. Dav was so disruptive in class that his teachers made him sit out in the hallway every day. Luckily, Dav loved to draw and make up stories. He spent his time in the hallway creating his own original comic books–the very first adventures of Dog Man and Captain Underpants. In college, Dav met a teacher who encouraged him to illustrate and write. He won a national competition in 1986 and the prize was the publication of his first book, <i>World War Won</i>. He made many other books before being awarded the 1998 California Young Reader Medal for <i>Dog Breath</i>, which was published in 1994, and in 1997 he won the Caldecott Honor for <i>The Paperboy</i>. <i>The Adventures of Super Diaper Baby</i>, published in 2002, was the first complete graphic novel spin-off from the Captain Underpants series and appeared at #6 on the <i>USA Today</i> bestseller list for all books, both adult and children’s, and was also a <i>New York Times</i> bestseller. It was followed by <i>The Adventures of Ook and Gluk: Kung Fu Cavemen from the Future</i> and <i>Super Diaper Baby 2: The Invasion of the Potty Snatchers</i>, both <i>USA Today</i> bestsellers. The unconventional style of these graphic novels is intended to encourage uninhibited creativity in kids. His stories are semi-autobiographical and explore universal themes that celebrate friendship, tolerance, and the triumph of the good-hearted. Dav loves to kayak in the Pacific Northwest with his wife.
