Horse Head is an enemy that guards the entrance to King Yama's lair, alongside Ox Face. He is functionally identical to Ox Face except for appearance and spawn point.

He will spawn shortly after entering 5-4 to the left of the Spelunker, about halfway to the edge of your screen (assuming you haven't moved).

It is highly recommended to kill him as quickly as possible, as he will soon start dropping bombs on the floor to take out the thin layer of blocks keeping you out of the lava. Shooting him twice with the shotgun or one sticky bomb will kill him, although the latter will likely destroy the floor below him and cause the bomb box he drops to fall into the lava.
