While dancing the Twisty Twist, Jack, Mary and Mel are interrupted by Phil the Coo-Coo Bird who bops into the clubhouse, totally out-of-control. Phil tells Jack, Mary and Mel that he is frustrated because today is the day when all the other Coo-Coo Birds gather in the Coo-Coo Tree and do the Coo-Coo Dance, and Phil doesn't know how to dance it. It's up to Jack and the gang to help!
