Synopsis:
The Sea Devils petition to join the Deep Six Liars Club. Each tells a tall tale to join, but they are all rejected because their tales are too unbelievable. Neptune has declared that all tall tales will actually happen now, because he is angry that no one believes true stories of the deep.

Over the next month, each of the Sea Devils’ tales comes true. Dane even meets Neptune himself and saves him from depth charges. When the Sea Devils try to join the Liars Club again, they are rejected a second time because now they have told true stories.
