A Grimbat (a creature that causes bad luck) is the reason why Prince Eccentro hasn't been winning against the Mon Colle Knights, so he decides to drop it into the volcano in the Fire Realm despite Tanaka's warning that the Fire Realm is where the Grimbat's originate. After doing that, Prince Eccentro, Gluko, and Batch notice a temple and thinks that there's a Monster Item in it. The Mon Colle Knights find out about where Prince Eccentro is and head to the Fire Realm. The Grimbat that was thought to be disposed causes bad luck for Eccentro and co. causing them to end up in the temple's traps.
