Clockwork Room
The Clockwork Room is a room found in Area Four of Luigi's Mansion.
After lighting up the Telephone Room, Luigi proceeded to the Clockwork Room, he saw three big windup soldier ghosts, pink, blue and green. They were the Toy Platoon, the Clockwork Soldiers. By activating the three clocks in the room, Luigi coaxed the soldiers to life. At first they seemed invincible, but by sucking up the windup key in the back of each one, Luigi revealed the ghosts' weakness. After all three were safely inside his Poltergust 3000, Luigi proceeded to the Roof.
The Clockwork Room is a large room with many items. There are three clocks Luigi can shake to activate. Four chairs, two on each side of the room, are present, as well as a marionette on either side. The Clockwork Soldiers themselves stand in front of three small houses, the middle of which opens to reveal an elevator to the Roof.
