This is a modern version of Tió de Nadal, a sort of #Catalan Christmas Log.

"Beginning with the Feast of the Immaculate Conception (December 8), one gives the tió a little bit to 'eat' every night and usually covers him with a blanket so that he will not be cold. The story goes that in the days preceding Christmas, children must take good care of the log, keeping it warm and feeding it, so that it will defecate presents on Christmas Day or Eve."
