Jin Jin, Benji, and Squawk get trapped in a cave-in as they explore the cave. They encounter a grouop of bats led by King Batolia as General Nightflyer allows them to hear them out. Hopper catches up to them and lies that Jin Jin, Benji, and Squawk are helping to conquer the Bat Kingdom on Dr. Mania's behalf. With advice from General Nightflyer who argues with Lord Wingsly, Jin Jin and his friends must prove that they are not associated with Dr. Mania.
