Ledge Hammers are obstacles and enemies in Super Mario Galaxy 2. They look like giant, orange and black sledgehammers. They only appear in the Clockwork Ruins Galaxy. They appear in the mission "The Ledge Hammer Trap". There are a total of six hammers which block the player's path to the Power Star. The Ledge Hammer's main attack is crushing Mario or Luigi under its tremendous weight, which can easily kill the brothers. Ledge Hammers are very hard to evade obstacles since they move very quickly. The hammers, however, can be slowed down via the time switch nearby.
