Messy, playing fetch with Tiny, returns with Stripy's teddy instead of the stick. He runs off with the little bear and Tiny chases them, but Messy and Teddy become separated and Teddy begins a series of adventures as he is accidentally passed from one robot to another. He appears in Scary's magic show, plays in Noisy's orchestra and flies with the robobirds. Tiny doesn't want to worry Stripy by telling him his bear has gone missing and is always just one step behind. In the end Teddy ends up back where he started, with Stripy completely unaware he was ever missing.
