Skid and Pump are a duo of small children in Halloween costumes. Skid wears a skeleton costume consisting of a black outfit with white lines and circles representing bones and a skull-head mask with black markings around the mouth. Pump wears a pumpkin costume consisting of a black suit with a white shirt underneath, white gloves and a pumpkin head mask. He also has a little cape behind his back
The pair work in tandem, with Skid resting atop Pump's head. The two share a bluish-gray microphone, though Pump holds it in his left hand by default. They do the Spooky Dance whenever they are not singing
During the remixed visuals of Week 2, they appear in the dark. Only their eyes and mouths are visible, and both of their eyes glow yellow
