Theodore

Theodore is the title character who lives in the Big Harbour with all of his friends. He's one of the smaller tugs that wears a red baseball cap. He is sometimes offended if someone calls him "cute" or "small". He and his closest friend Hank are the only two Harbour Tug (tugs that are not yet eligible to work outside of the harbour). They both share the harbour tug side of the dock and love working together.

He's a kind little tugboat that is always friendly to the other ships in the harbour, [1] [4] with the goal of becoming friends with everyone he meets. His biggest dream is to become an Ocean Tug and to travel across the sea to different harbours, [9] but before he does, he works as hard as he can to make the Big Harbour the friendliest harbour in the world. That's why he is always there whenever someone needs him.
