When Mayor McDaniels wants to have a Fourth of July celebration at the lake, she can't because fireworks have been outlawed in South Park. She decides to have a giant snake instead, since snakes are still allowed. She enlists a pitchman for the Dyno Might Firework Company named Charlie, who tells her about how a snake works and how they will get a giant snake to light up and expand. Later on, when the giant snake grows too big, Mayor McDaniels asks Charlie when the snake will die out. Doing some quick math, Charlie says that it will expire in November of next year.
Charlie has combed brown hair. He does not seem to have visible eyebrows, but he does have a small marking on his forehead. He also has a unique egg-shaped head and a slight cleft chin. He wears a dark blue business suit over a white shirt and black tie as well as black pants and black shoes.
