==Location==
# At the beginning of the level, walk to the door leading to the barracks, then turn around.
# Walk to the green metal rack and jump on top of it.
# Turn to the right, look up to the red metal beam, and jump on it.
# To the direct right, again, is a much larger blackish pipe. Jump on it.
# Walk along the pipe, taking care not to fall off, and you will see the skull at the end.
