The Wrecking Ball is an obstacle in Limbo. It is encountered in the Forest section of the game. You see it when you are nearly done jumping across the dead tree stumps. Even though it seems like a challenge to get past it, all you have to do is jump at the right time, then it will stick in the tree you just jumped from. If you fail to jump at the right time, it will knock the Nameless Boy flying into the sharp spikes below. If you hang onto the side of the tree when it swings, the Nameless Boy will be crushed by the wrecking ball when it sticks in the tree.
