? Balloon

? Balloons are objects that appear during the London Party mode in the Wii version of Mario & Sonic at the London 2012 Olympic Games. When someone walks into one, they receive an item, such as Power Sneakers, Banana Peels, Super Stars, Chaos Emeralds, Bonus Stickers, 5 Green Shells (shell mini games), Shields (Coin Collector: Shell Game), and Red Shells (2-on-2 Shell Showdown). ? Balloons are similar to Item Boxes from the Mario Kart series, but they do not spin.
