Gold Block

Gold Blocks are golden Brick Blocks that appear in New Super Mario Bros. 2. They appear when Mario or Luigi hit a Coin Block at least 10 times. When this happens, Mario or Luigi can wear the Gold Block over his head, thus producing coins from it if he keeps moving, making it very similar in function to the Question Boxes from Super Mario 3D Land. If Mario or Luigi runs fast enough, the amount of coins produced from the block increases. When a Gold Block is worn, the face side of it resembles Mario/Luigi's face, as shown in the image below. The Gold Block disappears and confetti pops out after 100 coins have been collected from it, or if Mario or Luigi is hit while wearing it. If Mario/Luigi jumps onto the flagpole while still wearing the gold block, he can continue to get coins from going down the pole and jumping off of it. Hitting one from either side or while wearing another Gold Block causes coins to fly out of the top until it disappears. The Gold Block will also protect against the stone spell used by the Koopalings in World 6 and World Star, though only once.

Flying Gold Blocks also appear in the game. Because it would be difficult to hit a moving Coin Block, Flying Gold Blocks are not hidden within them and are instead seen flying around in their idle golden forms. They occasionally appear for every 1000 coins and fly above Mario on the world map, and can be used right away upon entering a level, similar to the red Flying ? Blocks in the first New Super Mario Bros.. Also when the score reach the maximum of 999,999,999 points, Flying Gold Blocks was always appear no matter how many coins Mario earns.
