Nickelodeon All-Star Challenge is a three-episode game show television special that aired during The Big Help on October 3, 1994. The hosts of the special were Guts' Mike O'Malley, Double Dare and What Would You Do?'s Robin Marrella, who also served as referee, and Nick Arcade's Phil Moore, who also represented Double Dare due to his hosting the now-defunct traveling live show at the time. Representing Legends of the Hidden Temple was the character of "Olmec," voiced by Dee Bradley Baker. USA Today described the show as merging "the best games from Guts, Double Dare, Legends of the Hidden Temple and What Would You Do? into one big show." The show additionally combined all-star players from its contemporaneously-airing game shows Legends of the Hidden Temple and Guts with celebrities for fun.
