Requirements.

Journeymen hunt at the mountain - looking for a map piece to the Burroughs region. Only by catching a Ninja mouse will they find this.

Hunters, note there are no shops here on the mountain, stock up before you come.

High up on the mountain there are new mice to be found:
Frosty Snow
Frozen
Abominable Snow.

You may also find mice dropping pieces of Scrap Metal as loot - I wonder what we can do with those?

Good luck finding your map pice, hunter....
