Blargg's Boiler

Blargg's Boiler is a subterranean cavern found somewhere between the Bone Dragon Pit and the pipelines in Yoshi's Story. It is completely flooded with lava, and so the only way to cross is by traveling atop the bridges of giant bones.

The cavern is the native home of the Blarggs, which make their only appearance in this level. It is also the home of Lava Bubbles, Lava Ghosts, and Puffers.
