Mamoswine (Japanese: マンムー Manmuu) is an Ice/Ground-type Pokémon introduced in Generation IV.
A frozen Mamoswine was dug from ice dating back 10,000 years. This Pokémon has been around a long, long, long time.
Mamoswine's impressive tusks are made of ice. The population thinned when it turned warm after the ice age.
It is discovered that a Piloswine can evolve into Mamoswine when it levels up when knowing the move Ancient Power. It is the final evolutionary form of Swinub.
