Boobela is a giant - a young, shy and rather lonely giant. Worm is a worm - wise and opinonated, but above all, he's a clever and loyal friend. They live in a world that's a lot like ours, but not quite. When Boobela meets Worm, she has the chance to overcome her fears, pursue her strange and magical powers ... and have lots of funny, exciting and heart-stopping adventures with the kids at the balloon club, on her gran's magic island and at the beach.
