Green-fingered gardener Mr Bloom welcomes a team of young helpers, who tend to his plants and produce. In the garden, a tidy-up is needed in one of the vegetable patches - Mr Bloom can't tell the weeds from the leaves of the sprouting carrots. Inside the Nursery, Raymond wants to play Princes and Princesses with Joan but she's lost her tiara in amongst all the mess. The Tiddlers agree to help tidy up, but will they find Joan's crown?
