Brrr Bits are Enemies in Super Mario Galaxy. They appear to be small chunks of Ice, but when they're angered, they will burn with Blue Fire, and attack the Player. To defeat them, the Player, must use a Star Spin, which will put out the flame surrounding them, and they will fall to the ground. Mario or Luigi can then run into them to kill them. However, sometimes instead of hitting the ground, Brr Bits fall into the water, regenerating their flame.
