Episode: "Imaginationland III” (s11e12)
Original Air Date: October 31, 2007

1992's Super Mario Land 2: 6 Golden Coins properly introduced gamers to the identifiable construction foreman and Mario foil, Wario. His inception was as sinister as his crooked moustache, though he has since been lightened up with super fart powers (Super Smash Bros. Brawl) and frantic, LSD trip mini-games (WarioWare, Inc.). Among the other evil imaginary creatures in Imaginationland, Wario remains an unremarkable, threatening force and shows no penchant for flatulence or drug-induced shovelware. His appearance may be a tribute to his devious roots, or it may be as off-handed as the inclusion of Snarf.
