Trivia

 * It's possible to be permanently frozen right outside of Blizzard Buffalo's lair by a Snow Slider. If it freezes you in the middle of the icy slope right before the building, X will be frozen and unable to break free. The Snow Slider won't be able to damage him and set him free because the AI prevents it to travel past slopes.This may cause the player be there paralyzed until the snow slider hits him, cause if the player is frozen, until snow slider does not hit him, he will be not able to move, shot, break-free or any action.
