Catalonia Christmas poop tradition #2- Tió de Nadal. Families put a log with a blanket over it by the fireplace, and from Dec 8 to Dec 24, the kids "feed" it by putting snacks under the blanket so it will poop out presents for them on Christmas Eve. Then on Christmas Eve, they all gather around to beat the log with sticks while singing a song ordering the log to poop out their presents or else they will beat it more. https://en.wikipedia.org/wiki/Ti%C3%B3_de_Nadal
