While competing in the London 2012 Games, Olympic gymnast Gabby Douglas, 16, earned some gold: she won a gold medal in the individual all-around competition and another gold medal as part of Team U.S.A.'s Fierce Five gymnastics team. Now, Gabby is back home in the U.S. and helping Nintendo promote a different kind of gold: gold coins! The shiny objects take center stage in the New Super Mario Bros 2 game for Nintendo 3DS, in stores now. During a recent appearance at the Nintendo World Tour, in New York City, Gabby spoke with TFK about video games, the Olympics and what's next for her. (Reporting by Kelli Plasket / Videography and editing by Stephanie Kraus)
