Snow Spikes look similar to regular Spikes except they're blue in color. They also wear clothes probably to keep them warm in the cold. They also have black shells on their backs.
Snow Spikes appear mainly in World 5 in this game. Their only attack is to hurl snowballs at Mario. These snowballs can even hurt other enemies. They can be taken out easily with a Fire Flower.
Snow Spikes only appear in World 4 in this game. They are usually found on high cliffs attempting to strike Mario with snowballs from a distance. In battle, they only attack Mario by jumping on him and throwing snowballs at them. Snow Spikes usually drop Snowball stickers when defeated. Note that using an Ice Flower sticker on them will heal them.
