Minnie Mermaid is a live action, light blue haired mermaid who only appeared in the episode "Party Pooper Pants," during the Patchy segment. She was one of Patchy the Pirate's guests at his house party.
Minnie is a tan mermaid with long light blue hair. She wears a purple bikini top with seashells on it, and she has an iridescent purple tail.
During Patchy's party, which Minnie had attended, she had to stay in a very tiny paddling pool, which could only fit the top of her tail. Patchy came over to her when he was introducing everybody and accidentally stuck his hook into the pool, bursting it. After this, Minnie desperately started to try to stop the leak.
At the end of the episode, Minnie was standing up with everybody else, despite what she said earlier about how if she wasn't in the paddling pool, she would die.
