Nightmare Undying

Apparence
He's the same as normal Nightmare Undying.

Behaviour
He only appears at Disney Catacombs. He will become a threat if key was collected. While Henry is aggresivier when key is collected, Nightmare Undying is faster than him, so the player should be quick with escaping. When he spots player, then death is inevitable. So when you hear fast walking, hide IMMEDIADELY.
