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?

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.
