A Frosty Creature
The Frosty Creature is a Kyurem Event during the Advent 2013 and ends at the end of winter.
A mysterious Pokémon has recently been seen in Emera Town. It's said to cover everything in its surroundings in frozen ice.
How it is obtained
The Kyurem can be obtained by interacting with Eggs & Pokemon. It will need more than two or three interactions to earn it's respect.
An icon of the Kyurem will randomly appear on your userbar while interacting. If you see the icon, you click on it to get the egg, but keep in mind, you must have a free space in your party to obtain the egg!
