How to Choose
For more Pilkey choose Captain Underpants, Dog Man or Cat Kid Comic Club. For silly humour pick The Bad Guys, Super Diaper Baby or Big Nate. For graphic novels read Hilo, Babymouse or Investigators. For prank stories try The Terrible Two. Ook and Gluk is short and silly, so these picks suit readers who love comics. Pilkey says he has ADHD and dyslexia and wrote the books he wanted to read as a child, a story that many parents of reluctant readers find encouraging. His comics are a good bridge to longer chapter books. Pilkey's books use a technique called Flip-O-Rama, where readers flip pages to see animation, which children love. If your child enjoys comics, many libraries have dedicated graphic novel shelves. These books also work as shared reading between parents and kids.
