Directional Lift

Directional Lifts are objects appearing in Super Mario Bros. 3, only in the levels 2 and World 7-6. They are block-like platforms with an arrow emblazoned on them. If Mario stands on one, the platform releases a decolored form of itself and moves him to the direction the arrow wheel is pointing. There is another Directional Lift that has an exclamation mark on it. If Mario or Luigi steps on this one, he can control the direction of the platform up, left or right when he jumps. However, if he stands still while the platform is moving and stumble upon an obstacle, like a wall, the platform will keep moving or disappear, causing Mario to fall.
