The Squirrels go for a woodland walk to help Duggee look for a very special leaf when they hear the strangest noise. In the distance, they can see a funny shape. What is that noise? What is that shape? Maybe it's a monster? No, wait! It's only Hedgley the hedgehog, who has been trundling around the forest collecting all sorts of leaves and twigs on his spiky quills, which make him look and sound like a leafy monster.

Duggee is sowing seeds. The Squirrels ask if they can grow something too. Onion! Carrot! Cucumber! Pumpkin! And strawberry! Who grows what, and how big will they be? One of the Squirrels is in for an enormous surprise!
