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. However, most Charvaarghs only show up when the player enters a Clear Pipe for aesthetic purpose only.

Charvaarghs return to Captain Toad: Treasure Tracker, no longer used solely for aesthetic effects. They appear in lava stages either coming out of grates which Toad must walk across, or blocking his path where he must run across Boost Pads. They debut in the first level of Episode 3. In this game they do not instantly defeat the character.

Charvaarghs will make his Mario Party debut in Mario Party 10. They appear in Chaos Castle in the unlucky spaces to take away the players mini stars.

Trivia
