Snow Spike

A Snow Spike is a derived species of an ordinary Spike. Their visual appearance includes a cyan body, snow goggles, and orange snow boots, hat and gloves. Snow Spikes have the ability to take a Snowball out of their mouth, and throw it.

New Super Mario Bros.
Snow Spikes first appeared in New Super Mario Bros., although they only appear in World 5-1. The Snow Spikes' attack as normal Spikes do, except they pull out snowballs from their mouth instead of spiked balls. Unlike Spikes' spiked balls, these snowballs are affected by gravity, landing on the ground, rolling, and progressively getting larger as they roll until they hit a wall or fall down a pit. While rolling, the snowball will grow into a snow boulder as it rolls, bowling through anyone in its path, other enemies included (though this will not give points or extra lives).

Paper Mario: Sticker Star
Snow Spikes make their Paper Mario debut in the Nintendo 3DS game Paper Mario: Sticker Star. They look exactly like they did in New Super Mario Bros.. They are only found in the first two levels of World 4. In the overworld, Snow Spikes toss snowballs at Mario when they see him; being caught in one results in Mario taking damage as soon as he hits a wall, though they can be destroyed by using the Hammer. In battle, Snow Spikes can either jump on Mario or hurl a snowball at him. The Shiny Goombas are also on top of snowballs from Snow Spikes outside battle. If Mario jumps on a Snow Spike while holding a snowball in battle, the Snow Spike will be damaged unlike a Spiked Ball from a Spike. They are invincible to ice-based attacks, but take double damage when heat or fire attacks are used. Occasionally, instead of throwing the snowball, the Snow Spike will Ground Pound Mario. This attack can be blocked by simply wearing any version of the Spike Helmet sticker. If Mario is caught in this snowball's attack, he will be dragged out of battle and will take damage after hitting a wall. This attack cannot be blocked, not even Mario's Tail sticker will protect him. Snow Spikes are usually fought in groups of 2 to 3. After battle, a Snow Spike may drop a Snowball Sticker.
