This costume brings Barnacle Boy's character to life with a pullover shirt, which boasts a sailor collar and fabric ties that loop effortlessly at the neckline. The shorts, designed for easy wear, feature a comfy elastic waistband. No Barnacle Boy look would be complete without his distinctive sailor hat, which comes with a stiffened brim.

But that's not all. Dive into the details with the plastic eyeglass frame, complemented by an attached fiberfill-stuffed nose. This ensures you capture his memorable look! The foam-backed boot covers are designed with precision and gloves add the finishing touch so you will be set to team up with Mermaid Man to save the day! Monster
