HallowMarine

During HallowMarine, the Oklahoma Aquarium in Jenks opens its doors to trick-or-treaters of all ages to enjoy a safe, fun, indoor alternative to traditional Halloween activities. Bring the kids in their costumes to trick-or-treat among the tanks, play games, jump around on a huge pirate ship and wave hello to the diving mermaid and pirate in the Coral Reef. 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.
