Halloween is right around the corner so here are eight ocean-themed Halloween costume ideas for our ocean-loving students!

1. Scuba Diver

Griffen at Diventures in North Liberty shows how easy and cute a scuba diver costume can be. The biggest challenge? Drink two 2-liters of soda for the cylinders! Add a pacifier with a ribbon attached to the cylinders to substitute for the regulator.

2. Sea Urchin

A fan favorite at Diventures in Sun Prairie is the sea urchin costume. It’s cute and clever and we can almost guarantee your costume will be one-of-a-kind.


3. Shark

Landry-Shark at Diventures in Springfield is chomping at the bit to get his fins on candy this Halloween. This costume is perfect for those with little time to create something from scratch, and it’s easy to put on and take off. Add matching shark slippers like Landry to complete the look.


4. Octopus

If you’re crafty and on a budget, then an octopus is the perfect costume. Have your child pick their favorite color and get to stuffing! Plus, they’ll be extra warm with their matching beanie.

8. Coral Reef

At Diventures, we are all about ocean health and conservation. And nothing says “I love the ocean” more than a walking coral reef. This costume is a bit more hands-on than others, but it is the perfect activity for families who love our oceans and want to promote the beauty of the reefs.
