Reel (the camera head) and Spot (the spotlight head) are a two headed a two headed dragon who literally lives to capture things on film. Their heart is an old style reel of film that can be switched out when used up. Reel films while Spot adds proper lighting. Spot has a longer neck and can twist around. Reel has a shorter, stiffer neck so he can support the camera and remove shaking. Being attracted to beautiful or action filled moments, Reel and Spot are built to move very quickly so they don't miss much. The clapperboard tail is pretty self explanatory :)

And the little dragon thing they are filming is just a random furball.
