Gargantua Blargg

Gargantua Blarggs are massive fire monsters that reside in lava in the game Super Mario World 2: Yoshi's Island. These huge creatures attempt to block Yoshiâ€™s path by rising from the lava as the dinosaur approaches. To pass by a Gargantua Blargg, Yoshi must throw an egg at the monsterâ€™s mouth. The fire creature will then sink into the lava, allowing Yoshi to continue his journey.

In the game Tetris Attack, Gargantua Blargg appears as a playable character. He replaces the fire fairy Flare from the original Japanese version of the game.

The Gargantua Blargg is to lava as the Nep-Enut is to water.

In Yoshi's Story, a Blargg-like monster appeared in its own level, Stage 2-2: Blargg's Cavern. It was slightly more humanoid in shape.

Blaargs were also mentioned extremely briefly in Mario and Luigi: Partners in Time by Kylie Koopa.
