Dress up in your best Halloween costume for a chance to win prizes and interact with some of the ocean's most curious creatures from the deep during HallowMarine at the Oklahoma Aquarium in Jenks. Trick-or-treaters of all ages can enjoy a safe, fun, indoor alternative to traditional Halloween activities as they follow the Trick-or-Treat Trail through the aquarium.

Get your face painted with your favorite animal, play games, jump around on a huge pirate ship and wave hello to the diving mermaid and pirate in the Coral Reef. Little ones can explore the Coral Cove, a sweet and spooky play area with age-appropriate games, candy, and prizes. It's the only place in the area where visitors can shake hands with a friendly pirate or two and leave with the biggest bag of loot on dry land. All of the exhibits at the Oklahoma Aquarium are open during HallowMarine as well.
