Maddie and Triggs are camping in the woods with Dad. But when rain comes to spoil their campfire fun, they all rush inside the tent. Dad is not happy, but a visit from a cheerful little raindrop soon has the whole gang dancing around the tent.

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.
