Somewhere deep in the heart of the Pacific Northwest is a wooded glen known as Wetmore Forest. Meet the friends who live there!

When Tumblebee's belly aches from eating too many mushberries, Bugsy asks Sapwood Mossbottom, the wise healer of Wetmore Forest, for help. But to cure Tumblebee's tummy troubles, Mossbottom needs Pitter-pat root and he's all out. Bugsy agrees to fly to Bogwaller Swamp to bring some back, although he's not sure his wings are strong enough. Then, he gets caught in a terrible thunderstorm. Can Bugsy save the day?
