Zim discovers how much people like Santa Claus and decides to use this in a plan to take over the world by dressing up in a Santa suit full of data about Christmas. Dib once again tries to stop Zim, but this time has his father's help due to his dislike of Santa. The Santa suit malfunctions and engulfs Zim, effectively turning him into a real Santa Claus. Dib manages to stop the suit and then launches it into space, but Zim (who was freed from the suit upon its defeat) tricks the crowd into beating Dib up for destroying Santa. The episode ends two million years in the future in which it is revealed that the Santa suit (now massive) returns to earth every Christmas to wreak havoc and eat milk and cookies.
