The Dispatcher, who has been called "The Dishwasher" by Carla, is a rotating building on The Great Ocean Tug and Salvage Company Dock who gives the tugs their jobs for the day. He has a black mustache and a flag on his head.
He is usually very serious and stern with the tugs, but they are always respectful to him because of his father-like figure. He shows that he cares for the tugs by disciplining them for their faults, and by counseling them for their mistakes. And like a father, he always has a gentle side to him and is always there when the tugboats need his help the most.
