Fire Snakes appear in Super Mario World U. In the game they jump around and grow larger, making more light in dark areas. They can be defeated by Invincible Mario, Hammer Mario, and Earthquake Mario only if they are touching the ground, Ice Mario, Penguin Mario, Gold Mario, and Mega Mario. Also if they go into water they will burn out. They usually appear in desert levels, dark underground levels, or volcanic levels.
