The Three Smurfs Of Christmas were spirits induced by Grouchy ingesting The Christmas Spirit created by Papa Smurf in the video feature The Smurfs: A Christmas Carol. The spirits are modeled after three particular Smurfs in the village: Smurfette is the Smurf Of Christmas Past, Brainy is the Smurf Of Christmas Present, and Hefty is the Smurf Of Christmas Future. Their function is similar to the Three Ghosts Of Christmas in Charles Dickens' A Christmas Carol, with the Smurf Of Christmas Past showing Grouchy what his Christmases were like, the Smurf Of Christmas Present revealing things going on in the present-day Christmas that Grouchy may not be aware of, and the Smurf Of Christmas Future showing Grouchy what Christmas will be like if certain changes to his life weren't made.
