Learn and dance along with DJ Lance Rock! Come to a magical land full of music and dance with the Yo Gabba Gabba! Dj Lance Rock Adult Costume. History tidbit: Unlike most educational children's shows, Yo Gabba Gabba was not developed by network executives. Instead the show was developed by two Southern California fathers with no previous experience writing for television let alone children's broadcasting. They simply shared a mutual disappointment in kids television. They both wanted to design a kids show that was both educational and entertaining while featuring real artists and real performers.
