Trivia

 * Despite it's name, it has little to no relation to the motion picture, except for the title Undertale and the character Sans, who plays a far major role in this game than the movie (where he's just a background character in a few scenes). Due to how much everyone hated this game for having nothing to do with Undertale Burger, it was a total failure, only selling 1 copy that was the source of the pirated version a couple other people downloaded.
