Captain Underpants and The Perilous Plot of Professor Poopypants - Hiatus

Hiatus

Although the first few books came out on a regular basis, the 9th book, Captain Underpants and the Terrifying Return of Tippy Tinkletrousers (advertised in a teaser at the end of the 8th book), wasn't released until 2012. While some of his fans assumed that Dav Pilkey had writer's block, he was actually on hiatus caring for his terminally ill father, who died in 2008. In 2009, he signed a deal with Scholastic for four new books, the first of which was The Adventures of Ook and Gluk: Kung-Fu Cavemen from the Future, released on August 10, 2010. The second was Super Diaper Baby 2: The Invasion of the Potty Snatchers, released on June 28, 2011. The third book, Captain Underpants and the Terrifying Return of Tippy Tinkletrousers, was released on August 28, 2012. The fourth book, Captain Underpants and the Revolting Revenge of the Radioactive Robo-Boxers, is scheduled for release on January 15, 2013.
