With more than 36 million books sold, the My Weird School series really gets kids reading! In this eighth book of the My Weirdtastic School arc, Mr. Plummer—the world’s weirdest plumber!—plays detective and tries to figure out if A.J. is responsible for flooding the boys’ bathroom.

A.J. and his friends are listening to parents talk about their jobs during Career Day at Ella Mentry School, when suddenly the fire alarm goes off. But there’s no fire—there’s a flood in the boys’ bathroom!

It’s way too big of a job for Miss Lazar, the custodian, so the principal calls for some help. Enter Mr. Plummer, plumber extraordinaire. But will Mr. Plummer be able to fix the bathroom and figure out who caused the flood in the first place?

Perfect for reluctant readers and all kids hungry for funny school stories, Dan Gutman’s hugely popular My Weird School chapter book series has something for everyone. Don’t miss the hilarious adventures of A.J. and his friends!

  • A School Mystery: When a teddy bear clogs the boys’ bathroom toilet, A.J. becomes the number one suspect in the weirdest case Ella Mentry School has ever seen.
  • Silly Humour: Laugh-out-loud jokes, ridiculous situations, and A.J.’s hilarious thoughts fill every page, making reading fun.
  • A Whodunnit for Kids: Follow the clues with Mr. Plummer, the plumber-turned-detective, as he tries to crack the case of the Teddy Bear Toilet Clogger.
  • Perfect for Early Readers: With short chapters and fast-paced fun, this book is ideal for kids just starting their chapter book journey and for reluctant readers.
