Bud is a heartwarming story of discovery and change. High in the branches of an ancient maple tree, a tiny leaf named Bud marvels at the world around him, enjoying the sunlight, breezes, and the laughter of a boy named Max below. Max becomes Bud's favorite sight, filling him with joy.

As time passes, Bud notices changes within himself. His vibrant green fades, and he wonders what lies beyond his tree branch. Is there more to life than the view he knows?
