George loves to play with his favorite stuffed toy. Out in the yard, George tosses Mr. Dinosaur up and down, up and down, until Mummy Pig calls out that it's time to go shopping. There's so much to do and see at the market! But when they get home, George can't find his toy. Peppa and the family search everywhere, and even ask Officer Squirrel and Officer Panda for help. They have lots of lost toy dinosaurs, but they don't have Mr. Dinosaur. Where could he be?
