Dad is taking Maddie to school on his bicycle, but their journey through the park soon turns into an intergalactic space adventure. They listen to the sounds around them and imagine themselves as brave explorers, shooting like rockets into the unknown.

While crunching leaves in the garden, Maddie and Triggs make a new friend named Reginald the Caterpillar. Reginald tells them all about where he lives and what he eats, giving them a whole new perspective on munchy, crunchy, scrunchy leaves.

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?
