Once a year, for 5 nights only, the Oklahoma Aquarium opens its doors to trick-or-treaters of all ages to enjoy a safe, fun, indoor alternative to traditional Halloween activities. It's the only place around where visitors can shake hands with a friendly pirate or two and leave with the biggest bag of loot on dry land!
