Milo will not reveal what is inside his box, claiming that it is a secret – much to the other Tweenies' annoyance. They are cross and say that friends should share their secrets. They make their own boxes and tease Milo by refusing to say what's inside them. Eventually Milo opens his box and reveals his secret, but can he persuade the others to tell?

During a game of piggy-in-the-middle, Jake is teased for being small. Judy suggests that they all dress up to tell the story of the smallest rabbit who managed to banish a herd of elephants from his family's home. They all realise that the smallest person can be the star of the show and Jake enjoys his moment of glory.

Jake hears strange noises in the garden. They investigate and discover that it is the wind, which they decide is a monster. Max leads them in a Riverdance version of Michael Finnigan, then helps them to make monster masks. The Tweenies have great fun as their masks take over both in and out of the wind.
