Lethal Cavern

Lethal Cavern is an area in B3313.

Description
The area is a huge lava lake made out of blue lava, with several smaller platforms and boxes sticking out of it, along with a ground area at the end of a linear platforming section, which has a hole in the wall.

Origins
The area's layout and textures seem to mainly be inspired by one of Greenio's videos.

The music is the Underground arrangement from the Coincentration mini-game in Super Mario 64 DS.
