DJ Lance Rock and his colorful cohorts Brobee, Foofa, Muno, Plex and Toodee invite preschoolers to sing, dance and learn some lessons in this four-episode collection (which includes "Friends," "Eat," "Dance" and "Happy") from the innovative series. Blending live action, animated segments and infectious music, "Yo Gabba Gabba" teaches youngsters all about colors, the environment and good manners through a vivid world of puppetry.
