Caterican are found in the northern most parts of Azelon, having migrated from the distant Hagane region.
These frost worms are very docile and willingly approach hiking humans to lend what little warmth they can conjure up. Caterican are seen in the company of mountain hikers, as they use these Pokemon to seek out frozen berries. If threatened or spooked, these docile Pokémon will attack using a unique icy thread that will slow down their opponent and could potentially freeze them so they can ensure their survival. As they inch closer to evolution, Caterican feed on snow. When they have eaten enough, they bury themselves deep within the mounds of snow and are enveloped in a casing of ice.
