Bumper Cave

Refers to the cave used to access the ledge above the Dark World equivalent of the Death Mountain access cave. Can only be accessed by using the Magic Cape to pass through a giant bumper. If a progression item is located on the Bumper Cave ledge, it means that the Magic Cape is also a required Go Mode item.
