Fizzarolli is a tall male imp with a jester getup. His eyes have lime sclera and pink irises, his teeth are neon blue, and he has an imp tail with black stripes, however the stripe in the middle is white from "Oops" onward and in Blitzo's hallucination in "Truth Seekers". His cybernetic arms and legs are retractable, able to extend and bend far more than normal jointed limbs could and in "Oops" is shown to have a light blue circle on each shoulder and light blue spots on his knuckles.
