The North Core Tunnel is a room in the Magmoor Caverns. It appears in Metroid Prime. It is a hallway with a small pool of magma in the middle. Upon entering the room for the first time, a Magmoor will appear in the center of the pool, directly below a stalactite. If Samus launches a Missile at the stalactite, it will fall, kill the Magmoor, and can then be used as a 'stepping-stone' to cross the pool safely.
