Sparkleton is a floating island which only appeared in Mario & Sonic at the Olympic Winter Games for the Nintendo DS. This place is where Sparky lives and also where the snow festival is held. After beating Eggman Nega in Frostown, Mario and company gain access to Sparkleton by using the cannon. Pola is held hostage by Dry Bowser here.
