Maddie and Triggs are helping Dad in the garden. When he asks them to fill the watering can, they get distracted by the strange echoes inside and are magically transported into the belly of a whale. Can they help their new friend Harriot find her singing voice?

Triggs is feeling a bit blue and finds it hard to get out of bed. That pesky birdie outside his window isn't helping either. But Maddie thinks she knows what the Birdie might be singing about and helps her friend step outside to greet the day.

Maddie is at home waiting for the postman. She's expecting a letter from Uncle George, everybody's favourite uncle, but each time she hears a knock at the door, it seems to be someone else! Maybe today's not the day for George's letter?
