Balloon Goombas first appeared in New Super Mario Bros. U, in the Sparkling Waters level Skyward Stalk. They float straight upwards from the bottom of the screen on a balloon. When its balloon pops, it will begin walking like a normal Goomba. Mario can jump off the balloons for extra height. One of a group of 2 can help the player collect the third Star Coin. There is a total of 6 in the game making them uncommon.
