"Locked and Loaded!"
Stone zoo was released in the first wave of skylanders when Skylanders Giants first came out. However, after the first few findings and after a few weeks after the first wave they went away and weren't found. But, Zook wasn't the only one turned into a statue. Whirlwind joins him in being immortalized in stone. Stone Zook chows up in game as a regular Zook but with an added "Special" or "Rare" tag added on to the name.
