The Adventures of Super Mario Bros. 3 is an animated television series. It premiered on September 8, 1990, on NBC. It is the second animated series to be based on Nintendo's Mario video game series and is loosely based on the video game Super Mario Bros. 3. The animation was provided by Sei Young Animation. Overview Unlike its predecessor, the series dropped the use of live-action segments, Wart's minions and King Koopa's alter-egos, featured an entirely new cast (with the exceptions of John Stocker and Harvey Atkin, who reprised their respective roles as Toad and King Koopa), established a level of continuity in stories, and introduced a set of characters called the Koopalings, based upon the same characters from the Mario games but with different names. Episodes were divided into two segments of around 11 minutes each, always opened by a title card featuring world-map footage taken from Super Mario Bros. 3, and often featured the use of power-ups and other elements from the game. Format The Adventures of Super Mario Bros. 3 focuses on Mario, Luigi, Toad, and Princess Toadstool, who reside in the Mushroom World. Most of the episodes revolve around the four characters' efforts to prevent the attacks made by King Koopa and the Koopalings to take over Princess Toadstool's Mushroom Kingdom. Like The Super Mario Bros. Super Show!, the show was produced by DIC Animation City, with the overseas animation being done at the South Korean studio Sei Young Animation Co., Ltd., although the show was co-produced by Italian studio Reteitalia S.P.A. Since the show was based on Super Mario Bros. 3, the enemies and power-ups were also seen in the show. In addition to being more faithful to Mario gameplay, the series was given an established sense of continuity, something that the previous series lacked. Many episodes are set on Earth (consistently referred to as "The Real World" by the characters) and are set in locations such as Brooklyn, London, Paris, Venice, New York City, Cape Canaveral, Miami, Los Angeles, and Washington, D.C. One episode titled "7 Continents for 7 Koopas" is about the Koopalings invading each of the seven continents.
