Hook Mountain is one of the many rocky outcrops on Third Earth. Massive in size, Hook Mountain got its name from its peculiar shape which curves downwards at the top to form a hook shape. The mountain is plagued by extreme weather and snowstorms and avalanches are a common occurrence. The harsh weather and very low temperatures do not deter the Snowmen who live in a castle at the summit of the mountain.
