Skyloft is a new stage in Smash 4, and one of the first revealed. It's a tour-type stage based on Link's hometown from The Legend of Zelda: Skyward Sword. While all seems well initially in the town of Skyloft, fighters will soon notice that everyone seems to be missing, like Delfino Plaza. Are areas picked to be stages in Super Smash Bros cursed? There is an 88% chance that everyone died. Or perhaps those creepy raccoon-cat things that seem all innocent and cute during the day but become deadly at night are to blame. Or maybe it was Ghirahim, salty about being just an assist trophy. Or LordCarlisle. Despite this, Beedle's shop seems to be flying around, which means that someone must be piloting it. Perhaps Beedle killed everyone? USING THE MONEY THEY GAVE HIM?!?!? Oh, I'm sorry, I forgot that you wanted to know about the stage.
Skyloft is your average tour stage, visiting at the windmill, the Knight Academy, the Light Tower, the Goddess Statue, and many other locales. There is a 53% chance that this is still a pretty neat stage.
