Barnacle Boy Costume
Mermaid Man: – The Mermaid Man is a parody of Aquaman and Batman flagship of DC comics. He wears almost identical costumes in each episode (two shells on each side) and his abilities are similar to Aquaman, including controlling marine life.
Barnacle Boy: – Barnacle is a tall, thin, round-haired bald boy with a huge nose, swollen ears, a sailor’s hat, a black mask, and a blue scarf. As an old man, he looks a bit like a Squidward. He also wears dark blue rubber gloves, boots, a red T-shirt, and black rubber shorts.
Mermaid Man & Barnacle Boy Costume Guide
When it comes to iconic cartoon duos, Mermaid Man and Barnacle Boy from “SpongeBob SquarePants” stand tall among the classics. These retired superheroes have won hearts with their hilarious antics and unforgettable catchphrases. Whether you’re preparing for a Halloween party, a cosplay event, or just looking for a fun duo-themed outfit, dressing up as this dynamic duo is sure to turn heads. Here’s a deep dive into how you can assemble the perfect Mermaid Man and Barnacle Boy costume and channel your inner underwater superhero.
Mermaid Man Costume Essentials:
- Bright Orange Shirt: This serves as the base of Mermaid Man’s outfit. Opt for a short-sleeved tee or spandex shirt for authenticity.
- Green Pants and Black shorts: A pair of Pants and shorts that match the shade of the animated character will do.
- Purple Starfish Mask: This is a must-have. Either paint it on your face or craft a simple mask. Remember, it’s worn on the nose!
- Pink Slippers: Ideally, find fluffy ones to keep close to the character.
- Yellow Utility Belt: You can use a regular belt and adorn it with a large “M” at the center.
- Mermaid Man’s Emblem: This is the classic seashell bra design. You can either paint this onto the shirt, buy it online, or make it from craft materials and stick it on.
- Gloves: These should be long and green. If you can’t find gloves, blue wristbands or armbands will work as well.
Barnacle Boy Costume Components:
- White Sailor Hat: It’s one of the defining pieces of his outfit.
- Black Goggles: Unlike Mermaid Man, Barnacle Boy wears goggles on his eyes. A black-colored swim goggles will do.
- Blue Gloves: These can be wrist-length.
- Blue Scarf: To be tied around the neck.
- Red Shirt: A basic tee or a spandex shirt will suffice.
- Black Shorts: Any simple pair will do.
- Blue Socks and Blue Shoes: Pull up those socks to replicate Barnacle Boy’s iconic look!
Accessories and Extras:
For added authenticity, consider:
- The Invisible Boatmobile: If you’re at a cosplay event, you can get creative with clear materials or simply gesture to its “invisible” presence.
- The Conch Signal: Craft a paper or plastic version for added fun!
- Catchphrases: Sprinkle in some “Evil!” shouts or “To the Invisible Boatmobile!” for immersive fun.
Tips for Perfecting Your Look:
- Weathering: Since Mermaid Man and Barnacle Boy are retired superheroes, you might consider adding a bit of “wear and tear” to the costumes, giving them a slightly aged look.
- Posing: Studying a few classic poses from the show can help in photoshoots or when getting into character.
- Buddy Up: These costumes work best in pairs. Find a friend or family member to team up with for the full effect.
Dressing up as Mermaid Man and Barnacle Boy provides an excellent opportunity to embrace a nostalgic piece of cartoon history. By following these guidelines, not only will you have an authentic look, but you’ll also evoke fond memories for fellow “SpongeBob SquarePants” fans. Dive deep into the fun, and have a super Halloween or cosplay experience!
Below are the items required to create the costume:

Mermaid Man Hair:
Use the white Wig to match the Mermaid Man’s look. With some gel, you can style the hair the same as Mermaid Man.

Mermaid Man Face Makeup:
Making a starfish is easy. Take the makeup paint and ask your friend or spouse to make a starfish shape around your nose. It may take a few trials but it’s not very hard to try it!

Mermaid Man Shirt:
All superheroes wear an eye-catching color costume and Mermaid Man is no different. As a semi-retired super-hero orange-colored shirt is perfect.

Mermaid Man Gloves:
Mermaid Man wears Green colored gloves that match the pants.

Mermaid Man Pants:
Green-colored pants and an orange-colored shirt are a great color combination. Mermaid Man has a great dressing sense.

Mermaid Man Black Boxer:
As he a superhero wearing innerwear above the pants is a common thing I mean look at Super Man.

Mermaid Man Shell Top Bra:
With Boxers Mermaid Man also wears a Purple colored shell bra on top of the shirt. But do not judge him!
You may not find a purple shell bra, so you can buy a white shell bra and paint it with purple color.

Mermaid Man M letter belt:
All superheroes have a signature letter on their costume, and so does Mermaid Man with the letter “M” on his waist belt.

Mermaid Man Slippers:
Mermaid Man wears Pink color slippers instead of shoes because is a semi-retired superhero.

Barnacle Boy Hat:
All super-heroes wear hats and Barnacle wears a sailor’s hat. He is a superhero underwater therefore sailor hat makes sense.

Barnacle Boy Goggles:
Barnacle Boy had a sulfur vision power which maybe he controls it with his goggles. Wear swim goggles to match the Barnacle costume.

Barnacle Boy Scarf:
Barnacle Boy wears a Light Blue color Sailor’s Scarf and a Sailor’s Hat.

Barnacle Boy Shirt:
The Shirt of Barnacle Boy is red, which is attractive to look at and a common color of most superheroes.

Barnacle Boy Gloves:
The Blue Gloves of Barnacle Boy protect his hands from evil powers.

Barnacle Boy Black Boxer:
A red shirt with a black colored boxer is a great color combination for a superhero costume.

Barnacle Boy Socks and Swim Fins:
We could not find the exact fin boots of Barnacle Boy but instead, you can wear blue long socks with blue swim fins to match the look of Barnacle Boy’s Costume.
