They live together in a skulk, helping one another. Before eating their prey, they freeze it solid with their −58 degree Fahrenheit breath.
In hot weather, this Pokémon makes ice shards with its six tails and sprays them around to cool itself off.
These Pokémon live in packs in the snowy mountains and defend themselves with icy breath. I suspect this species changed its form to adapt to the frigid climate.
