No counting their time on-screen, the movie features some Spanish gift-bringers: Caga Tió from Catalonia, Olentzero from Basque Country and Anguleru from Asturias. In addition, it also features other gift-bringers from the different countries: Befana from Italy; Ded Moroz and his granddaughter Snegurochka from Russia; Dun Che Lao from China; Hoteiosho from Japan; and Gnome Tomte and Goat Yule from Sweden; besides another magical beings seen briefly in the C.H.U.S.M.A. meetings.
At a point of the movie Melchior complains Santa Claus accusing him to be "a toy to sell drinks". This is partially accurate: usually it is assumed that in the 1930s Coca-Cola used Santa Claus to promote the beverage for a Christmas campaign, drawing him in red suit instead the original green suit from the Norween myth because red was the company color. However, actually cartoonist Thomas Nast drawn Santa Claus in red suit in 1860s, but the Coca-Cola's Christmas campaign was so successful that people associated Santa Claus with Coca-Cola since then.
In the movie, the magical world is lead by an organization named C.H.U.S.M.A., short for "Comité de Hermandades Universales de Seres Mágicos y Asombrosos" (English for "Committee of Universal Brotherhood of Magical and Amazing Beings"). The joke, lost in the translation, becomes after "chusma" is a Spanish word that means "riffraff" or "rabble", referring to disgusting or unpleasant people.
The movie establishes a special place where all the Christmas and winter gift-bringer figures meet to prepare Christmas and talk about any problem. The same concept is re-used from the Spanish animated movie Pixi Post eta opari-emaileak (2016).
The three main characters are Melchior, Gaspar and Balthazar, known as Three Magic Kings. According to history and Holy Bible, Three Magic Kings (also called Three Wise Men) were whose traveled from distant kingdoms to give presents to Jesuschrist to celebrate his birth, following Bethelem's star across the night sky to arrive the manger where Joseph and Mary were spending the night when she gave birth Jesus. Respectively, Melchior, Gaspar and Balthazar gave to Jesus myrrh, gold and incense, as symbols of Jesus' Divine Trinity: Man, King and God. By their generosity, Jesus blessed them to give presents to the children around the world once every year to commemorate his birth, as gesture of good will to wish peace on Earth. The reason to be three men is assumed to represent the three known continents at those time: Europe, Africa and Asia.
