The world learned about the Rock Trolls, ancient creatures living in the Valley of the Living Rock, in Disney’s Frozen. The Trolls adopted Kristoff and Sven and consider them part of their family. They are very loving and family-oriented. Sometimes they can be loud, overbearing and intrusive, but they are always well-meaning. They can only be found if they want to be found, and that’s why their appearances in Disney parks are still rare.
