During the second holiday mission, "The Fight Before Christmas", you'll be romping around the North Pole. For this achievement, you need to come upon the six vignettes made using snowmen around the village in one run. To get credit, approach the snowmen and you'll hear them say something.Vignette #1: Braveheart
East of the town entrance in the middle of a frozen lake.Vignette #2: Negotiations
From the starting area, follow the road up to the edge of town. Follow the buildings to the right (east) and in one south-facing area you'll find it. You have to also visit the snowman threatening to jump from the roof.Vignette #3: Bar Brawl
South of Santa's sleigh ramp and north of #2, there's a small square. This one is here up on on a patio-like area.Vignette #4: Weightlifter
Across from #3 in the same square, a bit up the pathway between the buildings.Vignette #5: Alien
On the northeast corner of town, in-front of the northern-most house.Vignette #6: Snowman Centipede
On the west edge of town, just north of the western stables, there'll be a darkened, west-facing area along the edge of buildings. This'll be tucked in there.
