Scénario

The mod is set in an alternate universe that follows the events of the video, "SML Short: Jeffy's Tantrum!." After Marvin beats Jeffy during the argument, instead of becoming suicidal, Jeffy seeks the blessing of a set of deities known as the Hop Hop Bunny Gods, who claim him as a disciple and turn him into a demigod. Jeffy, now Dark Jimmy, destroys Marvin's old world with his newfound abilities but chooses to keep him alive in his newly created world, "Irida," in order to exact revenge. The two eventually have a final confrontation, the outcome of which is uncertain.
