The explorers approach a simple wooden door.
They enter to find a children's bedroom. The room is dark, with only night lights to illuminate the room. A one-eyed monster is hiding under the bed. His eye shoots a laser beam into the room.
One explorer ventures out into the room, deciding to avoid the lasers just in case they shouldn't be tripped.
The explorer starts moving the closet door, and notices that the angle of the door changes how the laser beam bounces off the mirror on the door.
The explorers are confused, they know they need to control the direction of the laser using the mirrors, but where should they direct the lasers?
One explorer has an idea, "what if we use the monster's laser eyes against him?!"
The explorers disperse througout the room, working together to angle the mirrors such that they can hit the monster under the bed.
They did it! The lights in the room come on and the monster's laser eyes turn off. A second door inside the closet opens and the explorers leave, having successfully defeated the monster.
