Preschool pop stars The Doodlebops know how to rock. This guitar is a miniature replica of the guitar Rooney Doodle jams on. “The fun and funky product line-up enables preschoolers to immerse themselves in the roles of the hip and active characters on the show,” Brook Hefner, public relations representative for Cookie Jar Entertainment, told TDmonthly. Launch date: August 2007.
