Wow, time goes by so fast (and kind of weird), based on one of my first digital drawings of 2018 (I think it should be in my profile if I'm not mistaken). I hope you like it! Now I want to clarify some doubts that maybe the most American public doesn't know:
Celestia and Luna are drinking “cola de mono”, it's a Chilean alcoholic drink that is consumed at Christmas time, it's made of coffee, milk, sugar, hard liquor and cinnamon. As you can see, they drank too much.
Applejack has in her hooves another Chilean Christmas classic, a kind of sweet bread with candied fruits and nuts called “Pan de Pascua” (according to wikipedia, it is a similar to “Christmas Pudding”).
