Spin Block (New Super Mario Bros.)
Spin Blocks[1] are platforms that are only found in New Super Mario Bros.. When stepped on, Mario or Luigi will start spinning and will fly high into the air, then glide back down slowly, allowing the player to travel longer distances. Pressing on the D-Pad while in the air causes Mario and Luigi to perform the Drill Spin, which has the ability to destroy Brick Blocks in a row or just to descend faster.
Spin Blocks are also found in the Mario vs. Luigi 2-player mode. It only appears on the ice level, where a Star will eventually appear. There are however always coins hovering above the Spin Block.
The movements Mario or Luigi make when they jump on the Spin Block is similar to the movements they make when they use the Propeller Mushroom/Propeller Block in New Super Mario Bros. Wii.
Spindrifts were originally going to appear in New Super Mario Bros., but they were replaced by Spin Blocks in the final build.
