A whacky good-luck-attracting tradition like this had to come from one of the oldest nations in Europe, Catalonia. The tradition predates the arrival of Christians and has evolved throughout the centuries.Adopt a pooping log!
Classically, people in Barcelona and Catalonia "feed" the Tió leftovers, fruit peels, like orange peel, or similar. The better you feed it tho, the better good fortune and presents you will get.
Pooping logs are magical figures that can appear in your life, usually in your room, or doorstep, bought at a market in Catalonia, given by someone as a gift, or alternatively, you can build yourself.
If you built it, find a small or medium log of wood from a tree. You must maintain your Pooping Log and show it affection after making it. Give it a Barretina, the Catalan red cap with a black base, and a warm cozy blanket.
You may also purchase a plush Soca from poopinglog.com, where you can get a cuddly replica of it - only available in the United States at this moment.
Soca is widely unknown here in the US with some exceptions, mainly by SNL start Kate McKinnon who herself adopted the Catalan Poop Log Christmas Tradition. Check out this video with Seth Mayers explaining the tradition.
The Tio de Nadal, or Caga Tio is not the only genuinely Catalan tradition with a poop theme. Kids ( and adults) growing up in Catalonia have another scatologic tradition to look forward to every Christmas: the Caganer
The Caganer is a unique figure in Catalonian Christmas celebrations that translates the “The Crapper.”
The Caganer is a Catalan farmer who is traditionally depicted wearing a Barretina, a traditional Catalonian red cap. He is different from the Pooping Log because he does not poop presents, but feces. yes that's right. It's commonly thought that it was created as a means of soil fertility and, as a result, bringing good fortune. In most cases, you'll find them in the manger scene in the middle of things, doing their job next to the infant Jesus.
The Crapper is such a popular artisan tradition in Catalonia tho that the small figurines are now modeled to look like well-known celebrities, politicians, and athletes. Are you looking for the soccer player Messi crapping? You will find it for sure. Maybe the Pope or President Biden? You will find them as well.
