Fizzlits are enemies that appear in Super Mario Galaxy 2 and Super Mario 3D World. They have an electric puddle form that electrifies the player if they try to jump on them in this form. Therefore, they can only be defeated while in their purple form.
In Super Mario Galaxy 2, Fizzlits have a tooth-like appearance, and in their electric puddle form, they have a simple flat, circle shape. However, in Super Mario 3D World, they have a more cube-like appearance, as well as having no "legs." In their electric puddle form, they have a less flat, more square-like appearance.
