Betty the Mouse's little ones see a big shadow from their cosy nest in the potting shed, and all agree it must be a dinosaur. Word spreads around the garden and reaches Tilly the Tortoise, who is on a visit for the holidays. She can't believe her luck - she loves dinosaurs! Tilly heads off on a search around the garden, bumping into Casey the Badger and Rosie the Rabbit, but no one has seen it. Auntie the Tawny Owl points her in the right direction - back to the potting shed! Will she ever find the dinosaur?
