From the Super Mario Wiki
Li'l Brrrs are enemies in Super Mario Galaxy and its sequel, Super Mario Galaxy 2. They are the icy counterparts of Li'l Cinders. To defeat one, Mario must use a Spin to put out the ice cloud surrounding it, and it will fall to the ground stunned just like any other enemy. If the player is not quick to hit the Brrr Bit while it is vulnerable, it will start to hop around, attempting to jump into icy water and regenerate its ice cloud. Icy water does not appear in the sequel, so it takes longer for a Li'l Brrr to regenerate on ice or snow. When Mario runs into one after the ice cloud disappears, it will release one coin.
With their ice cloud, Li'l Brrrs resemble Embers with white eyes. However, Embers are fire creatures, while Li'l Brrrs are Ice creatures. They also resemble Ice Elemental Ghosts from Luigi's Mansion and Freezies from the original Mario Bros..
A planetoid in the Battle Belt Galaxy is also shaped like a giant Li'l Brrr.
