|Ally||Koopa Troop, Bowser|
|Debut Appearance||New Super Mario Bros. Wii(2009)|
Stone Spikes are a blue version of Spike appearing in New Super Mario Bros. Wii. They behave just like spikes except they throw spiked stone balls instead of metal. They also live in dank places underground meaning they could very well be Spikes that have adapted to dark, cave-like conditions.
Stone Spikes appear only in New Super Mario Bros. Wii where they appear in only two levels. Unlike Spikes who throw their balls to their sides, Stone Spikes throw them downward towards the bottom of the screen. If Mario or Luigi get hit by the balls they will take damage. They can be defeated by jumping on their heads, but players must be careful they don't jump on them while they are holding their balls. They can also be defeated with a Fire Flower or Ice Flower, among other power ups.
