Freddie, a stray ferret, is found under the shed at Lilac Cottage. To make Freddie feel at home, Mandy comes up with a way to include her in a school Fun Day to raise money for new story books. Then Freddie's real owners spot their missing ferret on Mandy's stall. They're happy for her to hang on to the ferret until the end of the event - after all, it's in a good cause - but then Freddie goes missing.

Will she turn up in time for the ferret fun?
