These series take place in a valley near a snow covered mountain, where the most important main character lives in a cylinder shaped house. The characters are more or less humanoid creatures.
The series cover the daily lives and adventures of the characters in pretty much independent stories, which take place over the 4 seasons (fall, winter, spring, summer).
