Clockwork Soldiers

The Clockwork Soldiers, the Toy Platoon are a green, blue, and pink trio of Portrait Ghosts from Luigi's Mansion.

The Clockwork Soldiers are found in the Clockwork Room on the third floor of the mansion. Luigi finds the Soldiers immobile. If Luigi starts the three clocks in the room, they awaken and begin attacking with their toy cork guns. As they move around, Luigi captures each by sucking their wind-up keys with his Poltergust 3000. Only the blue Clockwork Soldier can give up pearls. After this, the playhouse's doors open, granting Luigi access to the Roof.
