From the creator of the internationally bestselling and award-winning BONE series comes a charming and adorable picture book -- the first to feature Smiley Bone in an adventure all his own!

On a beautiful sunny day, happy-go-lucky Smiley Bone is walking through the woods when he begins to count some friendly birds. The birds sing and climb so high that Smiley must find a fantastical way to keep up with them! With lively drawings and expressive word balloons, Jeff Smith has created a one-of-a-kind picture book that will delight the youngest readers.
