Vanilla Dome

The Vanilla Dome is the third world in the SNES title Super Mario World. It is a cave world with seven regular levels, a Ghost House, the Red Switch Palace, Star Road 2, a fortress, and #3 Lemmy's Castle. The cave contains enemies such as Swoopers and Buzzy Beetles, as well as lava. The world has a secret path that leads to the mountaintop above the cave, which has a few secret levels, and leads to Butter Bridge. There is also a lake in the middle, where Vanilla Dome 2 takes place.

Trivia

 * Though the Vanilla Dome never made an appearance in the Super Mario World cartoon, the show exclusive area, the Lava Pits, seemed to take several elements from the Vanilla Dome, such as Blarggs and Skull Rafts.
 * In Super Mario Kart, two racetracks called Vanilla Lake 1 and Vanilla Lake 2 appear. It is unknown if these tracks take place in Vanilla Dome, though it's unlikely since they're not located in a cave area.
 * This is the first world to have levels having level(s) having a bigger square instead of a normal one. The others are Forest of Illusion and Valley of Bowser.
