Dorothy the Dinosaur and her friends The Wiggles, Wags the Dog, Henry the Octopus and Captain Feathersword are spending a day at the Powerhouse Museum. There's so much to see and do … but before too long Dorothy loses her favourite handbag! So they set off to find it and uncover some remarkable things along the way. Join Dorothy and her friends on their adventure as they explore the museum and find trains and cars, engines and guitars, beautiful old dresses and vases, and — eventually — the missing handbag.
