Skystones are fan-favorite cards that are packed inside General Mills cereal boxes. They are available inside cereal boxes, such as Honey Nut Cheerios, Cinnamon Toast Crunch, Reese's Puffs, Trix, Lucky Charms and more for a limited time.

There are four sets of Skylanders Skystones to collect, and each set contains 10 cards, two of which are ultra-powerful "boss" villain cards that will unlock exclusive content in the free Skylanders Collection Vault app. 


The origins of Skytones go way back to the days of the Benevolent Ancients. While experimenting with early Portal technology and magic, they discovered a form of enchanted stone that would allow anything painted on it to become real. The Ancients worried that this power might fall into the wrong hands, so they turned it into a strategy game, purely for fun and leisure.[1]
