Hey Duggee S01E24 - The Acorn Badge

Norrie is upset when she sees a leaf fall from the tree. She thinks it's broken. She soon cheers up when she finds out that some trees shed their leaves in autumn, and actually it's quite good fun playing and jumping in piles of leaves. 

But ouch! What has Roly found stuck to his bottom? It's an acorn. Duggee explains that lots of forest animals collect acorns to eat in the winter, so the Squirrels decide to look and find lots of acorns to share out for everyone.
