Sorry, I don't have that information. Usually, such announcements are made by the park authorities a few weeks or months before the opening. You could also call the park's information hotline to inquire.
One possible plotline could be Arlong and Luffy having to team up against a common enemy in a very unlikely alliance. This would force them to put aside their differences and learn to work together.
In South Park, there was a strange occurrence. A new kid moved into town, but this kid was a bit different. He was a super - smart alien in disguise. The boys, being the curious bunch they are, quickly noticed something was off. Cartman thought he could use the alien to take over the world, Kyle wanted to help the alien fit in, Stan was just confused, and Kenny was along for the ride. They all got into crazy adventures as they tried to figure out the alien's true motives and protect South Park from any potential threats.
Well, the Central Park 5 case was a huge miscarriage of justice. In 1989, a woman was attacked in Central Park. The police quickly focused on these five young guys. They were questioned for a long time, and under pressure, they confessed. But it turned out those confessions were false. Years later, the real perpetrator was found. It was a sad situation where these boys' lives were ruined just because the police were so eager to solve the case and didn't do a proper investigation.
The park's size can be a big factor. If it's a large park, the big cops might have a hard time covering all areas, which could lead to some parts of the park being more vulnerable to problems. For example, in a large forested park, it might be easier for illegal activities to occur in the more secluded areas.
