The Pirates of Dark Water

Morpho creates a body-switching potion for Bloth so that he can use it on Ren and find the remaining Treasures.

Ren and the crew encounter Ioz's sister but she has her own motives when she persuades them to search for treasure.

While in Octopon, Ren discovers a plot that has caused the monkey-birds to revolt against their queen.

Both Ren's crew and Bloth's crew work together when they are forced to play a dangerous game.

A storm washes both Ren and Niddler overboard and they find themselves on an island where a strange man speaks to them about a missing Treasure of Rule.

An encounter with a ghost ship turns into a race against the clock as Ren and the crew try to free Ioz before he becomes a ghost.

A return trip to his home of Octopon turns out to be a problem for Ren when he finds out the city is controlled by Morpho and the Dark Disciples.
