Bear is getting ready for bed. He's had a little snack, brushed his teeth and put on his big bear pyjamas when - Knock! Knock! - someone is at the door.

Don't they know it's bedtime? It's Mouse and she needs a little snack. Then Crocodile arrives and her toothbrush is broken, and - uh oh - Lion's pyjamas are too small, and now wide-awake Owl is playing her trumpet very loudly. Can Bear help his friends so they can all get a good night's sleep?
