 Due to the difference in the intended demographic, the original plotlines (as well as the premise of rival tug fleets) were not used.Instead, the producers of "Salty's Lighthouse" wrote entirely new stories of the boats in 'Snugboat Harbor', relating to the theme of the main animated segment, with footage from the series edited and redubbed to tell these stories.Along with the newly created stories, various changes were made to the characters featured in them.
