Blargg

Blarggs are lava-infesting monsters from the Super Mario World series and Yoshi series. They are odd in that, despite appearing in Super Mario World and its three sequels, Blarggs appear different in each game.

Super Mario World Blarggs
The Blarggs in Super Mario World are dragons that reside in lava-filled caverns. These enemies hide in lava, and when Mario approaches one, the Blargg lunges at the plumber. Unlike Mario, Yoshi can jump on top of Blarggs to avoid getting hurt. This will not defeat them however.

Super Mario World 2: Yoshi's Island Blarggs
Blarggs also appear in Super Mario World 2: Yoshi's Island. In this game, Blarggs are no longer lava dragons, but instead lava versions of Nep-Enut. Despite this change of appearance, they attack the same way as their Super Mario World counterparts. (However, in this game, Yoshi cannot jump on top of them.) Some Blarggs have grown to epic proportions, becoming the awe-inspiring Gargantua Blarggs.

In Tetris Attack, a single Gargantua Blargg was brainwashed by Kamek and Bowser, forcing it to join their side. Once this Gargantua Blargg is defeated by Yoshi, it becomes playable in Tetris Attack's multiplayer mode.

In Yoshi's Island DS Blarggs and Gargantua Blarggs make appearances as enemies once again. Yoshi's Island DS also introduced a new type of Blargg called Crusher Blarggs, which are enormous in size and can crush solid rock.



Yoshi's Story Blarggs
Blarggs make another appearance in the sequel to Yoshi's Island, Yoshi's Story, in Stage 2-2: Blargg's Boiler. These Blarggs were as large as regular Gargantua Blarggs and were orange and yellow in color. The Blarggs of Yoshi's Story also possessed lazy-eyes and small arms.

A Beta Blargg in Super Mario 64
A Blargg was supposed to appear in Lethal Lava Land but was never put in the game.

Cartoons
Blarggs, though never referred to as such on-screen, appeared in several 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 the T-Rex and another Tyrannosaurus Rex, use a Blargg's head as a stepping-stone to cross a river of lava.

Comics
In the Super Mario Adventures comic, several Blarggs appear before Mario, Luigi and Yoshi while they are navigating their way through Bowser's lava-filled basement. Using these Blarggs as stepping-stones to cross a large pool of lava, Mario, Luigi and Yoshi manage to reach a nearby Warp Pipe that leads to the upper region of Bowser's Castle.

Trivia

 * The Red Dragon in Stage 6-4: Magma Castle of Yoshi's Story bears a large resemblance to the Super Mario World interpretation of Blarggs.
 * Czar Dragon, the boss of Barrel Volcano in Super Mario RPG: Legend of the Seven Stars, resembles a Blargg. Due to this resemblance, the crown-like horns atop Czar Dragon's head, and the title "czar" (Russian for "emperor"; literally "caesar"), it has been speculated by some that Czar Dragon is the ruler of the Blarggs.
 * Untextured creatures which resemble the Super Mario World interpretation of Blarggs can be found in the coding of Super Mario 64, which reveals that they were going to appear in a lava filled world.
 * Blarggs were briefly mentioned by Kylie Koopa in Mario & Luigi: Partners in Time.
 * A Sammer Guy in Super Paper Mario is called "Raging Blargg".
