By clipping partially into the lower-left corner of the room, a downward teleport can be used to reach Swamp Palace Hammer Switch. Two setups are commonly used to clip into this position: one using a bomb, and the other using an dash clip.

This is one of the few underworld clips that is both allowed and in logic in the Hybrid Major Glitches ruleset.
