DJ 1 has a deep, bassy voice, and often sings the songs during Bozark's dance numbers.
In 2010, DJ 1 appeared in a short called Copy Security that was released on The Jim Henson Company Podcast. In this short the puppet was performed by Alison Mork. In a reference to being a puppet, he presses an X-Ray button on a copy machine and is shocked to see a hand inside of him. He also was puppeteered by Grant Baciocco in a puppet lesson in another 2010 podcast.
