It’s Take Your Favorite Toy to School Day for Pax, and Polly’s Mom has charged Polly with making sure Pax gets to preschool with his favorite stuffed panda. But when Polly gets the panda dirty, she sneaks it into the wash so her mom won’t realize she messed up… and the panda gets lost in the dryer! Polly tracks the lost panda to the Lost and Found pocket world, but finds it’s been ruined by the washer/dryer. Not wanting to disappoint her mom, Polly decides to bring a living panda lookalike, Addleforth, back to Pax for the day, but this only causes chaos at the preschool. Will Polly own up to her mistake?
