Summary While helping a professor over an apparently haunted shipwreck, 2 of the crew warn the gang about the ghost of its captain and 2 sea monsters - a kelp monster and an octopus monster - who are supposedly guarding the treasures. The professor dismisses the claims but it isn't long before the ghost and sea monsters turn up on the ship and start pursuing the gang. The crewmen flee the ship, but the launch is found empty and drifting. The professor also vanishes, leaving the gang to deal with the ghost and sea monsters. A dive to the wreck reveals a cache of scuba tanks, suggesting that there may be an attempt to steal the shipwreck's treasures. Now the gang must find a way to put a stop to the thieves.
