Lethal Lava Land

Lethal Lava Land is the seventh course in Super Mario 64. The course is a variety of platforms set upon a large pool of lava, all situated around a volcano which can be entered as a sub-area.

While straightforward on the outset, Lethal Lava Land hides a few strange anomalies and sightings within it.

Blargg

Found unused in the game's files is the untextured entity of Blargg, an enemy making their first and only major appearance in Super Mario World. They were set to reappear in Lethal Lava Land, along with Bowser in the Fire Sea and oddly Wing Mario over the Rainbow.

The enemy ultimately went unused in the retail release of Super Mario 64, most likely due to time constraints as seen with the enemy's unfinished state. However, some people report that Blargg has appeared within their personalised copies, likely the A.I. pulling assets to use and trick the player.

Dancing Flowers

Most levels in Super Mario 64 has an environmental effect. For example, Lethal Lava Land has an effect that creates lava bubbles that gurgle on the surface of the lava in the stage. One of the unused environmental effects is one featuring dancing flowers, which would spawn around the player on the plane they are standing on. While this effect goes unused in the final game, the graphic for the dancing flowers is still found in the game and strangely are coupled with most of the graphics associated with Lethal Lava Land.

Volcano Blocks
Inside the volcano where the Power Star for Hot-Foot-It into the Volcano is, a strange arrangement of metallic blocks can be seen around the stars. What they are is unknown; they appear to be ruins, although their metallic texture suggests otherwise. The texture on these blocks are unique to Lethal Lava Land, and their strange appearance has led players to question their significance.

Blue Lava
Blue Lava can be found in some copies of Super Mario 64 making the lava in Lethal Lava Land turn light blue with a glow and making skybox at night with a blue hue in it. Blue Lava is a real phenomena located at the Kawah Ijen Volcano in Banyuwangi Regency, it is caused by the high concentrations of burning sulfur up 600 degrees. If any human would come close to they would die from breathing in all the sulfur and from the heat, so then the course name being Lethal Lava Land would make senses. The unique level theme is most likely created by the Personalisation A.I. creating the player a unique theme.
