Giant cannonballs, also referred to as massive cannon balls or huge bullets, are very rare moving obstacles found in Super Mario Bros. 3, New Super Mario Bros. Wii, and New Super Mario Bros. U. They are much faster and bigger than the original cannonballs, making them harder to avoid. In Super Mario Bros. 3, they appear only in Dark Land's first tank level and the battleship level. The cannons that fire the giant cannonballs resemble Warp Pipes, but they are colored black (blue in reissues) so as not to confuse the player. In New Super Mario Bros. Wii, they appear only in World 8's Airship. In New Super Mario Bros. U, they appear only in The Mighty Cannonship from Soda Jungle. Even though normal cannonballs are absent from New Super Luigi U, giant cannonballs reappear in the level Bowser Jr. Showdown.
Giant cannonballs reappear in Super Mario Maker, Super Mario Maker for Nintendo 3DS, and Super Mario Maker 2. The player can enlarge a normal Cannon with a Super Mushroom, enabling it to fire giant cannonballs. The second official course created by Bowser, named Bowser's Cannonball Run, involves Mario running to keep a giant cannonball onscreen until the end.
