Headcanon that the winter fairies are super into extreme sports (example: literally all the "how to x" promotional videos for secret of the wings) because they only work for like ¼th of the year and dont have anything else to do in the winter woods.
The other three seasons work in tandem for the other ¾ths of the year, so they're a lot more busy than the winter fairies and have less-developped sports, such as competitive leap frog 💀 (see: pixie hollow games).
