Episode Title:Ghosts.Episode Description:A heavy fog rolls over Bigg City Port. One night, Big Mac is on his way home to the Star Dock Pier having spent the day working with Scuttlebutt Pete, who has told him all kinds of stories about ghost tugs. As he gets closer to home some mysterious white tugs sail in front of him without making a sound. Scared by what he's seen he hurries back through the fog to tell the others, who all ridicule and laugh at him (although Sunshine remained more open-minded than the rest). The following night, however, the rest of the Star Fleet, as well as Zorran and Izzy Gomez, all get a scare when they see the mysterious tugs in and around the port. Hercules, the Ocean-going Tug, explains what the fuss is all about.
