The nostalgia-filled Multi-Coin blocks are back again, and have a special feature along with it! For those of you who don't know, the Multi-Coin blocks are the blocks that have more than one coin in them that will come out with each individual jump underneath it. In New Super Mario Bros. Wii, if you are on top of one of these blocks, you can perform a special technique that may or may not be more useful than the traditional way. By jumping, Gound Pounding (Performed by pressing Down in midair) on the Multi-Coin Block, and not letting go of Down, you can receive the coins from the block in a constant stream! The coins come out of the block from underneath, and this whole technique can prevent having to constantly jump to get your coins.

Ground pounding on other blocks with things on them will do the same thing as they do as if you had jumped from underneath to get the item or coin, but with the item or coin revealing itself from beneath the block. This could be useful if there's an enemy beneath the blocks, and you just want that Mushroom to come out, move to the side, and be able to be grabbed.
