Barcelona has a curious little sculpture that they call the “pooper”.

A Caganer is a figurine depicted in the act of defecation appearing in nativity scenes in Catalonia and neighbouring areas with Catalan culture such as Andorra, Valencia, and Northern Catalonia (in southern France).
It is most popular and widespread in these areas, but can also be found in other areas of Spain (Murcia), Portugal, and southern Italy (Naples).

The name "El Caganer" literally means "the pooper". Traditionally, the figurine is depicted as a peasant, wearing the traditional Catalan red cap (the barretina) and with his trousers down, showing a bare backside, and defecating.

In Catalonia, as well as in the rest of Spain and in most of Italy and Southern France, traditional Christmas decorations often consist of a large model of the city of Bethlehem, similar to the Nativity scenes of the English-speaking world but encompassing the entire city rather than just the typical manger scene. This pessebre is often a reproduction of a pastoral scene—a traditional Catalan masia (farmhouse) as the central setting with the child in a manger, and outlying scenes including a washerwoman by a river, a woman spinning, shepherds herding their sheep or walking towards the manger with gifts, the Three Wise Men approaching on camel back, a scene with the angel and shepherds, the star pointing the way, etc. Commonly materials such as moss will be used to represent grass, with cork used to represent mountains or cliffs.

The caganer is a particular and highly popular feature of modern Catalan nativity scenes. It is believed to have entered the nativity scene by the late 17th or early 18th century, during the Baroque period.
Eminent folklorist Joan Amades called it an essential piece and the most popular figure of the nativity scene. It can also be found in other parts of southwestern Europe, including Murcia, the region just south of the Valencia in Spain (where they are called cagones), Naples (cacone or pastore che caca) and Portugal (cagões). There is a sculpture of a person defecating hidden inside the cathedral of Ciudad Rodrigo, Province of Salamanca, though this is not part of a nativity scene. Accompanying Mary, Joseph, Jesus, the shepherds and company, the caganer is often tucked away in a corner of the model, typically nowhere near the manger scene. A tradition in Catalonia is to have children find the hidden figure.

The Caganer, by creating faeces, is fertilizing the Earth. According to the ethnographer Joan Amades, it was a "customary figure in nativity scenes [pessebres] in the 19th century, because people believed that this deposit [symbolically] fertilized the ground of the nativity scenes, which became fertile and ensured the nativity scene for the following year, and with it, the health of body and peace of mind required to make the nativity scene, with the joy and happiness brought by Christmas near the hearth. Placing this figurine in the nativity scene brought good luck and joy and not doing so brought adversity."Read more
