What does snorunt evolve into?

Snorunt will evolve into two different things depending on its gender

if it is a girl it will evolve into froslass

if it is a boy it will evolve into glalie

WRONG! Well, you are right about only the female Snorunt evolves into Froslas (use Dawn Stone). But both genders can evolve into Glalie by leveling up, not just the males.
