The boogey orc is found in the third room of the prison dungeon. He is at the very east end of the third room. The boogey orc cannot be killed, and instead Nona must stun him and quickly run by. If the boogey orc grabs Nona while she is naked, it results in an immediate game over. The easiest way to defeat him is to jump kick and retreat.
