If you're familiar with the Welsh wassailing custom of Mari Lwyd, or the Slavic Devac, this might look familiar. The Yule Goat is also a Scandinavian folklore figure and we're borrowing this mythology for Tistow as well.
In Tistow, people celebrate yule and its many guardians and keepers. Young men go out wassailing and performing pranks on midwinter evening, with one of them dressed up as a rowdy, gift demanding white goat.
