The Enderman spawns in Default difficulty as a mini-boss in Soggy Swamp, the Desert Temple, and the Overgrown Temple. In Adventure difficulty, it would spawn sometimes in the Creeper Woods, the Cacti Canyon, and the Overgrown Temple, and in Apocalypse, it would spawn sometimes in the Redstone Mines, the Fiery Forge, and the Overgrown Temple.
