Princess Mindy Neptune is the tritagonist of The SpongeBob SquarePants Movie and a supporting character in it's video game adaption, Book adaption, Cine-Manga book adaption, 3D game adaption and the books Road Trip in 3-D!, Are We There Yet?, Bring on the Rock!. She is the daughter of King Neptune and Queen Amphitrite and is Prince Triton's sister. She knows the names of all the sea creatures. It is also certain that King Neptune will crown her Queen of the Sea one day.


Mindy has light green skin, dark blue hair, wears round black glasses, a light-green tail, and a yellow hair bow. She wears a golden bracelet and also wears a pink midriff top with a red heart in the middle.

She is known to use "mermaid magic" to help others overcome their fears. There really is not any mermaid magic; it is just fake. Mindy tries to get SpongeBob and Patrick to keep going when they give up their walk, she tries to convince them that she had "mermaid magic," and uses it to "turn them into men" by pulling seaweed out of the ground and putting them on their noses, successfully helping them by tricking them into thinking that they are real mustaches. Dennis reveals the trick after SpongeBob and Patrick pass through the trench.

Mindy is very beautiful and good-hearted and has a deep love for all the ocean-dwellers.


Unlike her father, she shows more compassion toward her father's subjects. She also encourages Patrick and SpongeBob to continue to Shell City, despite the others doubting them. She was even guilty that she lied to them that they became men, which caused them to run into danger with overconfidence but was happy they succeeded. Likewise, her personality is quite similar to Ariel from Disney's The Little Mermaid.


  • In the video game adaptation of the movie, Mindy reveals she actually does have mermaid magic, which she uses to get the Patty Wagon back in exchange for 50 Goofy Goober tokens.
