Crarime, Cadarime, Fearime

Crarime: Made from the souls of lost explorers who died in mountains or ice caps. It haunts its grave with bone chilling howls. It has become a popular cursor icon for computers.
In the game, you'd find it at a shipwreck in a town of ice.
 
Cadarime: It leaves its grave to haunt other places. A touch from its claw freezes blood.
 
Fearime: Represents winter depression, its ultimate goal in "after life" is to haunt. Wherever it goes, it brings death: water freezes, trees die, and other Pokemon even other ghost run from the freezing air that surrounds it.
When it finds a lost traveller, it will often simply stand there, in the traveller's path. It does not require any physical contact to traumatize the traveller for life.
