Abominable Snowman
From Pikmin Fanon
The Abominable Snowman is a large beetle shaped vaguely like a snowman. It has ice themed attacks, so any cold immune Pikmin should work well against them.
In Pikmin: The Last Battle
In Pikmin: The Last Battle, the Abominable Snowman is the eleventh boss fought, being fought in the Tundra of Peace. Its arena can be accessed after finding Black Pikmin, and is in the south of the area. Defeating it yeilds an old telephone and a large fruit.
