Sluzzle Tag was conceived by Gumball to help combat the merriless lulls of January. It is celebrated on January 10th (or possibly January 11th, if the episode takes place during a leap year) and gives kids a day off of school.
Its name is meaningless, being chosen by Anais following a brainstorming session. Other potential candidates included "Fun Day," "Dependence Day," "Wig Tide," "Danke Party," "Schnitzel Time," and "Googoo Bash."
As with the holiday, the traditions of Sluzzle Tag bear no significance, being made up largely on the fly by Gumball to add legitimacy while also being convenient in his execution of it.
The holiday is meant to celebrate the spirit of Sluzzle Dude, whose appearance consists of a beard, sneakers, and a leather coat. Mirroring Santa Claus, he delivers presents in a magic van led by Dobermans (named Trasher, Smasher, Rancid, Rages Slayer, and Rabies). He gets into houses to deliver presents through the toilet; because of this, the residents of Elmore decorate their bathrooms accordingly with skeletons and barbed wire, and milk and cookies are dumped down the toilet for him. Another key aspect of Sluzzle Tag is that, because Gumball had to find a way to make the holiday work, the presents delivered are the discarded gifts nobody wanted from Christmas.
Traditional Sluzzle Tag music consists of grindcore. Carollers also sing grindcore versions of Christmas tunes.
Junk food is traditionally eaten on Sluzzle Tag. A specialty is the Sluzzlewurst (invented by Richard), made up of cheese, bacon, processed meats, and other junk food jammed into a sausage. Sluzzlewursts are so fatty that they cause people to sweat butter.
A Sluzzle Tag stop-motion animated special plays on the holiday entitled "The Night Before Sluzzle Tag." However, due to Sluzzle Tag's instantaneous creation, only a few seconds were made in time for its initial broadcast.
