Frestnoches evolved a thick fur across their abdomen to keep them warm in the harsh northern climates and have a varying amount of large, chitinous spikes protruding from their body that they use as tools to survive in the harsh wilderness. They largely eat trees and large bushes, but they also cut down trees to make large, circular piles for their egg nests. After laying their eggs, they'll cover their nest and remain inside to produce the warmth necessary for the eggs to grow, only leaving when necessary to collect more trees for food or when threatened.
