Carbon Costume 
Princess Mindy from Spongebob Squarepants
Princess Mindy (voiced by Scarlett Johansson) is the daughter of Neptune in the animated series SpongeBob Squarepants. She first appears in the SpongeBob Squarepants Movie, and later in a few episodes. She is good friends with both SpongeBob and Patrick. Princess Mindy is a mermaid, so the most important part of her costume will be the mermaid skirt. From there, some green body paint, a blue wig, and the right accessories will complete the look.
Squidward Tentacles from SpongeBob SquarePants
Squidward Tentacles (voiced by Rodger Bumpass) is SpongeBob‘s prickly neighbor and co-worker on the cartoon series SpongeBob SquarePants. Squidward has a light blue-green body and wears a yellow polo shirt. As a squid, Squidward has several more legs than any human who might decide to dress up as him. If you want to just wear the costume without the extra limbs, that’s certainly fine. If you decide you’d like to have a little fun and DIY a few extra legs, consider using pool noodles and following a tutorial like this one.
Patchy the Pirate from SpongeBob SquarePants
Spongebob might live in a pineapple under the sea but that doesn’t mean he doesn’t have fans on land. In fact he has a whole fan club. And Patchy the Pirate (played by Tom Kenny) is the president. Self-appointed, of course. But that still counts! And with his trusty – if snarky – cohost Potty close at hand, he’s always ready for a special Spongebob adventure!
Patchy is pretty much your stereotypical pirate. He wears a black tricorn hat over a red bandana along with an eye patch and a scraggly black beard. A purple velvet jacket over a white shirt pairs with a set of black “pirate pants” and black boot covers for a look fit for a presidential pirate. A black sash repurposed as a bandolier, a hook toy for your hand, a fake peg leg, and a green parrot toy finish off the look!
Mermaid Man
In SpongeBob SquarePants, Mermaid Man is an old semi-retired superhero who resides in a retirement home with his sidekick Barnacle Boy. He suffers from poor eyesight, hearing loss, and forgetfulness.
Barnacle Boy
In Spongebob Squarepants, Barnacle Boy is Mermaid Man’s sidekick. He is slight more sane than his counterpart, but is treated like a child by him despite his now elderly status.
SpongeBob SquarePants
SpongeBob SquarePants (voiced by Tom Kenny) works as a fry cook and lives in a pineapple under the sea. As befitting his appearance, he is a squeaky-clean square, annoying everyone around him with his cheerful optimism.
Patrick Star
In SpongeBob SquarePants, Patrick Star (voiced by Bill Fagerbakke) is an overweight, dim-witted pink starfish. He’s unemployed, but works on occasion at Krusty Krab with his best friend SpongeBob.
