Previously, Big Bird was accidentally changed into little Big Bird when Mumford tried to do a magic trick. While it was fun being little, little Big Bird now wants to be big again so that he can play with his friend Snuffy. He decides that he has to make his way to Alan and Gordon who are playing chess so that they can help find Mumford to change him back. On his very long and slow trip, a ladybug named Mike crash lands right into him. He teaches little Big Bird that he has to keep trying no matter what obstacles he faces and what size he is. Little Big Bird remembers to believe in himself and with a little persistence, he finally makes it! Once he is finally noticed, Mumford is able to turn little Big Bird back into big Big Bird. In true Mumford fashion, Mike the ladybug is turned big as well and wants to join Alan and Gordon in a game of chess.
