The hunt for the super crystal begins. Only those who have obtained all five world crystals from the various BattleCaves and combined them to form the super crystal will have achieved their goal: power over the whole of Eldrador. A tough task, as the world crystals are not so easy to combine. Those who succeed should carefully protect their precious loot. The super crystal is in good hands in the BattleCave. Only those who know the combination can open the safe. Who will be the future ruler of Eldrador? The Eldrador Creatures BattleCaves transform every child's room into an action zone. Who will face the breathtaking battle? All BattleCaves can be combined. Sinister tunnels and nasty traps lurk for the attackers. They meet for a duel in the large arena. What a battle.
