The CD and DVD were originally released separately but have since been released as a combo. There are 25 songs in the CD and 38 in the DVD. The DVD features puppetry, animation and live action supplied by personal friends of the group. The music videos that appear on the DVD were also aired (in part or whole) on the Disney Channel's children's programming block, Playhouse Disney. Two follow-ups were released, Here Come the 123s in 2008 and Here Comes Science in 2009.
