• Number: 4
  • Type: Harbour Switcher Tug
  • Affiliation: Zero Fleet

Zug is an ambitious, young tug, Captain Zero's fourth tug, and one of the Z-Stack switchers. He is used for a wide variety of tasks around Bigg City Port. He speaks with a Midwest Estonian accent.


He mainly works with Zip, and likes to think of himself as the intelligent one. Compared to Zip, he certainly is intelligent, but he isn't as smart as the other tugs. He comes up with devious plans for him and Zip to use (although the plans usually fail). Despite being best friends with Zip, Zug basically commands him, who's too frightened to make any good suggestions. Zug's capabilities range from the towing of barges to liner docking operations. Like the rest of the Zero Marine, Zug is based on the Moran Fleet tugs of the 1920's. He's sneaky, cowardly and he needs the other Z-Stacks around for courage. Zug is a scheming sort of tug, though his plans rarely if ever work as planned. Zug is intimidated by the main Z-Stack Zorran and has a tendency to be somewhat nervous and jittery around him. Zug and Zip are the Z-Stack equivalents of Ten Cents and Sunshine, in that they are the smaller tugs of the fleet, who work together and are plotting against the other two. Zug has major roles in most episodes, and a majority of stories focus on him as a major character in some way, usually concerning Zip. Zug's whistle has a hooting quality that sounds very much like a squeeze horn, but deeper.
