Tugs is a 1989 British children's television series created by the producer and director of Thomas the Tank Engine & Friends respectively, Robert D. Cardona and David Mitton.
In the North American adaptation, Salty's Lighthouse, the stories were re-purposed for a younger audience.
They regularly find ways to hinder and infuriate their rival Star Fleet tugs.
The Galleon was an old wooden sailing ship that sank many centuries ago and became frozen inside an iceberg.
The White Fleet came to Bigg City Port to look for this ship, during winter, where the thick fog came down at night.
Because of the warmer waters out at sea, the iceberg melted, causing the galleon to rise to the surface, much to the surprise of Ten Cents and Sunshine, who were taking fuel out to Lillie Lightship at the time.
