Sheldon is a tall, lonely mushroom surrounded by beautiful flowers. He is often teased because he is so plain and doesn't have a pleasant aroma. Because of his quiet nature and different appearance, he is ignored by the bugs and flowers, as they enjoy themselves dancing and singing. To everyone's surprise, Sheldon is needed in a life-saving emergency, and his significance is discovered when he turns into the hero of the day. The rhyming songs are extra tools used to express the valuable lessons of being kind, being humble, and helping others.
