Charvaargh

Charvaarghs are a subspecies of Magmaarghs that make their first appearance in Super Mario 3D World. They attack by jumping out of lava at any of the five characters.

They appear in only one level, World Castle-7, Simmering Lava Lake where players must make it past them. If a character touches them, a life is lost, regardless of the character's form. Charvaarghs are one of the few enemies that are truly invincible as no method of attack will affect them, not even the Golden Statue form.

Trivia

 * The Charvaarghs closely resembles the Blarggs from Super Mario World.
 * They are also the only enemies (including bosses) other than the Fuzzies in Fuzzy Time Mine that can kill in one hit.
