Maddie and Triggs are at the seaside building sandcastles. But when one seashell starts to move, they realise it's no shell at all, but Sailor Nancy - the fanciest crab to ever walk sideways! Can they save Nancy's fancy sandcastle before the tide comes in?

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.
