Castle is a theme that was introduced in 2013, succeeding Kingdoms. It features blue lion knights battling red dragon knights, and, with both historical and fantastical elements, will combine aspects of its predecessors, Kingdoms and Castle (2007).
- The two factions have the same animals as the forces in Kingdoms, but the Lions have a blue shield like the Lion Knights in Knights' Kingdom, along with a crown like the Crown Knights, while the Dragon knights are red.
