Worms!

Fleas!

Join Bertie as he takes a flea-ridden Whiffer to the vet, does a naughty dare at school and gets a ride in shiny red fire engine!

Mud!

Join Bertie in three hilarious stories as he faces a barrage of footballs as the school's new goalie, battles to stay clean for the school photographer and has a spookily terrifying sleepover!

Bogeys!

Join Bertie as he tries to stop picking his nose, gets more than he bargained for with a magic trick and drives a museum potty on a school outing!
