Snowdin

Snowdin is a town the protagonist encounters after they leave the Ruins and travel through Snowdin Forest. The town is home to numerous members of the Royal Guard, presumably because the town neighbors the entrance to the Underground, where Sanses fall. Departure from the town takes the protagonist to Waterfall by foot or, by hitching a ride with the River Person, to either Waterfall or Hotland.

Despite being Underground, Snowdin is covered in a perpetual layer of ice and snow and, because of how cold it is, it mainly homes Papyrus with thick Sweaters and skeletons that do not get cold.
