Lethal Cavern is an area in B3313.
Description[]
The front half of the area consists of a huge lake of blue lava, with several platforms sticking out of it. This linear platforming section leads to the solid ground of the back half of the area, which has an ominous hole in one wall.
Origins[]
The layout and textures of this area seem to be mainly inspired by the "Deeper Cavern" video from Emmy's Super Mario 64: CLASSIFIED video series.
The music playing is the "Lethal Lava Land" theme from the vanilla game OST.
Stars[]
This area has 2 stars to collect:
- Use the Metal Cap to reach the star above the lavafall at the end of the area.
- Break open the item box at the end of the area.
