Join Jimmy On Stage — Enter the Parrot Head Costume / Dance Contest
The contest will be held at the plaza stage at each venue with the performing band each night at 7pm. Winners will be selected from a Hokey Pokey competition while being judged on costume and dance creativity.
The Sports Magic Team will coordinate the contest and the Coral Reefer Dancers will serve as judges. Those selected each night will join Jimmy on stage during a song. Each night’s winners will be entered in a drawing for an all expense paid trip to the Parrot Head “Meeting of the Mind” Convention in Key West. The Grand Prize includes airfare, hotel, transportation and VIP Status to all events during the MOTM weekend.
