You can either paint one on yourself or pick up a starfish sticker and fasten it on your nose with some bands or string. You can also pick up a Full Mermaid Man Costume if you’d like to dress as that character or steal pieces from the outfit for Spongebob.
Spongebob as Scary Mustache Man
Who’s that mysterious, mustachioed figure lurking in the alleyways of Bikini Bottom? It’s none other than SpongeBob in his ‘Scary Mustache Guy’ ensemble! In Season 4, Episode 19, SpongeBob dresses as the Mustache Guy and grills Patrick about jelly fishing supplies. This costume is the easiest twist you can put on the classic Spongebob costume. You simply need to add a big fake mustache to your outfit. If you want to go the extra mile you can add some fake “Buck” teeth as well.
