Like their smaller counterparts, Giant Spiked Balls can destroy blocks and even the smaller Spiked Balls. They appeared first in New Super Mario Bros. where they appear in various levels, their first appearance being in the second castle in the game. They return in New Super Mario Bros. Wii in World 8-2. In World 8-Airship, Bowser Jr. uses Giant Spiked Balls that possess the ability to explode, and must be used against him. In New Super Mario Bros. 2, they appear in two castles in the game. In World Mushroom-Castle, there is a Spiked Ball that is even larger than the already giant Spiked Balls. They are absent in New Super Mario Bros. U, and New Super Luigi U as they are replaced by Mega Grrrols. They also appeared in Super Mario 3D Land with a purple color.
