Mermaid Man and Barnacle Boy are one of the most iconic duos from SpongeBob SquarePants. They are quirky, colorful, and easy to recognize. Dressing up as them works perfectly for conventions, themed parties, or just for fun.
This guide breaks down each part of their look using simple, easy-to-find pieces. We’ll go through both characters, head to toe, with tips to get the best match.
Mermaid Man & Barnacle Boy Costume Guide
Mermaid Man’s look is a mix of superhero and goofy underwater vibes. His bright colors and unusual accessories make him stand out.
Here’s how to put it together:
1. White Wig
Mermaid Man’s hair is short, white, and styled into a small swoop in front.
Use a short white wig to match this. Make sure it has a neat cut so it sits well on your head. You can trim the front to get the little wave in his hair.
2. Purple Face Paint
He has a purple star-shaped mask painted right on his face.
A water-based purple face paint works best since it’s easy to apply and remove. Use a small brush to get clean edges. Check a picture for shape accuracy before you paint.
3. Green Rubber Gloves
Mermaid Man wears long green gloves that reach up the forearm.
Go for waterproof or rubber gloves with a smooth finish. Pick ones that are snug so they don’t look baggy.
4. Orange Long-Sleeve Top
His top is bright orange with a high neckline.
A fitted, long-sleeve athletic shirt will give the same clean look. Avoid loose fabric so it stays close to the body like a superhero suit.
5. Green Leggings
He wears green leggings under his shorts to match his gloves.
Compression tights in a dark green shade work well. They also keep the costume looking sleek.
6. Black Swim Shorts
Over the leggings, Mermaid Man wears black shorts.
Pick short athletic or swim shorts. They should sit at mid-thigh to match the cartoon style.
7. Seashell Bra
One of his most funny features is the shell bra over his shirt.
A white seashell bikini top will work. Adjust the straps so it sits high on the chest, just like in the show.
8. Purple Spray Paint
You can use purple spray paint to color small accessories, like the shells if they aren’t already purple. Always spray outdoors and let items dry fully before wearing.
9. Yellow Belt with M Buckle
His belt is bright yellow with a big “M” buckle.
You can find a yellow belt and attach a foam or cardboard “M” to the front. Paint the letter blue for accuracy.
10. Pink Slippers
Mermaid Man’s “hero shoes” are fuzzy pink slippers.
Pick soft slippers with a bright pink tone. They don’t need to be waterproof unless you plan to wear them outside.
Bonus Tip:
Stuff the shirt slightly around the belly area if you want to match Mermaid Man’s round shape. Use lightweight padding so it’s comfortable.
Barnacle Boy Costume Guide
Barnacle Boy’s look is simpler but still has fun details. His outfit is cleaner and easier to move in compared to Mermaid Man’s.
Here’s the breakdown:
1. White Sailor Hat
His hat is a small, flat sailor cap.
Get a fabric sailor cap that sits snug but not too tight. Make sure it’s pure white without extra decorations.
2. Swim Goggles
Barnacle Boy wears black goggles with blue-tinted lenses.
Pick comfortable swim goggles that fit over your eyes or forehead. You can wear them resting above your hat for a relaxed look.
3. Light Blue Neckerchief
Around his neck is a light blue scarf tied loosely in front.
A satin scarf works well since it has a bit of shine. Tie it in a knot at the front and let the ends hang evenly.
4. Red Long-Sleeve Top
His shirt is bright red with long sleeves.
A basic fitted athletic shirt will keep the look sharp. Avoid anything with logos.
5. Black Swim Shorts
He wears plain black shorts.
Go for short athletic shorts that match the style of Mermaid Man’s. Keeping the shorts length the same makes the duo look more cohesive.
6. Blue Rubber Gloves
Barnacle Boy’s gloves are blue and reach past the wrists.
Choose rubber or waterproof gloves with a smooth texture.
7. Blue Rain Boots
His boots are tall, solid blue, and have a simple shape.
A pair of rubber rain boots is perfect. If you can’t find the exact shade, you can spray paint lighter boots with flexible paint.
Bonus Tip:
Barnacle Boy is much taller and slimmer than Mermaid Man in the show. If you want to mimic that, stand with your legs slightly apart and lean forward for the “cartoon” posture.
Putting It All Together: Duo Style
Dressing as both Mermaid Man and Barnacle Boy works best when you coordinate. Here are some tips to nail the duo look:
- Match colors exactly. Bright colors make the costumes pop, so try to keep tones consistent.
- Walk together. The characters are always side by side.
- Add props. You can carry small toy shells, bubble blowers, or “Invisible Boatmobile” signs for fun.
- Stay in character. Mermaid Man is loud and heroic, Barnacle Boy is grumpy and sarcastic.
Comfort and Practical Tips
- Wear breathable fabrics under gloves and leggings to stay cool.
- Use body-safe face paint and test on a small area before applying fully.
- If going to a party or convention, pack small items like water and a phone in a hidden pouch.
- Bring spare socks or slippers if you plan to walk a lot in Mermaid Man’s pink shoes.
