The villains are pair of green-eyed tugs who once snuck into Bigg City Port to search for loot.
To increase their security, they used Sea Rogue as their decoy. To make sure that he performed their bidding, they held his uncle ransom and threatened to sink him if Sea Rogue disobeyed them. With the unexpected help of Zip and Zug, the Star Fleet and Sea Rouge were able to capture the pirate tugs and hand them into the authorities.
The villains are mysterious-looking vessels with black paint and a distinguishable pair of green-tinted spotlights on the bows. They are known as 'The Green-Eyed Things'.
Behind The Scenes
The Villains' design may have been inspired by the Mysterons from the Gerry Anderson series Captain Scarlet & the Mysterons, a show which David Mitton had worked on as a trainee special effects technician. Two traits the Mysterons are known for that were adapted into the villains are their booming voices and green eyes.
