Do you believe in magic? Well, you just need to look beneath your feet …

Underneath the floorboards of number 39A Cove Street live Joey and Fred O'Brien, nine-year-old twin elves who get up to all sorts of mischief together.

Whether it's their missions Up-Up to borrow supplies from their human neighbour, Bee-Bee – and stay out of the path of her big St Bernard dog – or creating magic under the floorboards from all the things we leave behind, every day is an adventure for the Squirby elves.

But when the twins see Bee-Bee needs their help, they risk everything to rush to her rescue!
