Blargg

Blarggs are large, lava-dwelling monsters, commonly found in underground caverns in which magma is fierce and abundant. Originally, Blarggs resembled lazy-eyed dragons, but more recent depictions show them as being anything from blob-like beings with large mouths, arms and beady eyes to humanoid, limbed creatures.

Blarggs first appear in Super Mario World as fairly rare enemies, encountered primarily in the Vanilla Dome. These Blarggs resemble the aforementioned draconic version of the creatures. In this appearance, Blargg, upon seeing Mario or Luigi approach on a Skull Raft, will try to lunge at them, roaring menacingly. Blarggs could not be defeated by any conventional means for the most part and can only be avoided, though Yoshi is capable of jumping on them and, with some difficulty, eating them.

In Super Mario World 2: Yoshi's Island and Yoshi's Island DS, Blarggs are changed completely in appearance, but retain their attack pattern of lunging at the player, but now cannot be jumped on by a Yoshi, but can be subdued by having a Yoshi Egg thrown at them. In Yoshi's Story, Blarggs are once again altered, being larger and given small arms, they appear in only one level, Stage 2-2: Blargg's Boiler. Perhaps the Blarggs that appear in Yoshi's Story are a different type of Blargg.

Television
Blarggs, though never referred to as such onscreen, appeared in two episodes of the Super Mario World animated series.

In the episode "The Wheel Thing", Mario and Luigi, having been banned to the Lava Pits, begin attempting to cook a pizza over a fire. The smell from this cooking pizza causes a Blargg to emerge from a nearby lake of lava and begin to chase Luigi, attempting to eat the plumber. Luigi is rescued from being devoured, as Mario swoops down and saves his brother as Cape Mario.

In a later episode titled "Mama Luigi", a Blargg makes a brief appearance. Luigi and Yoshi, while running away from a pair of Tyrannosaurus Rex, use a Blargg's head as a stepping stone to cross a river of lava.

Literature
Several Blarggs make a minor appearance in Nintendo Power's Super Mario Adventures comic, appearing in the lava flooded basement of Bowser's Castle. These Blarggs are used as stepping stones by Mario to reach a Warp Pipe leading to another level of the castle.
