These Pokémon carry large crystalline flowers of ice kept cold by the frigid air loosed by their many, diamond-like frost organs. These flowers shimmer like an aurora and to witness them even once is considered a great boon.
Aurosaur's flower is said to take on vivid colors if it gets plenty of nutrition and sunlight. Using its diamond-shaped crystals, it can instantly create a wall of ice to block an opponent's attack.
