[Kenai]

An Easter Egg monster only encountered when it is snowing in the northern peaks of the map, and only between December 1st and January 1st according to your game system's time clock. He'll either be in one of 3 states:

1) Dec 1-24 Super Powerful, especially the closer to the 24th.
2) December 25-30 Weakened state
3) Dec 31 - Jan 1 Drunken state. Hilarious but tricky fight
