RSF has put up a new flash video, though it passed under my radar for some time (in fact, he's due for a new one). This one's shorter than many of his earlier works , such as Michael Fantasy and Sega Fantasy IV. Anyway, Super Mario Underworld is an epic battle between the Mario and Luigi (or something? maybe?) set in the Super Mario World universe. As usual, it's epic and awesome, though the song has lyrics this time, featuring someone who probably didn't get very good grades in English. It's apparently a psuedo-parody of this flash video, which appeared at flash★bomb '05, a japanese flash animation event. Looks like they didn't do it again in 2006, unfortunately.
