An adaptation of the 1993 live-action movie Super Mario Bros., this one-shot heavily truncates the story. It was published in Shogakukan's Monthly Corocoro Comic Summer Holiday Special 1993.

Daisy requests the help of the Mario Brothers to save her flooded excavation site. She is abducted by Iggy and Spike and taken to an alternate dimension ruled by the tyrant Koopa. Mario and Luigi follow her and soon confront Koopa, who needs a meteorite piece to merge their two dimensions. Fungus-related shenanigans ensue. Can the plumbers stop Koopa from taking over the "surface world" with his de-evolution guns?
