True, it might not be the film wicker man, but it seems so random next to mutiny bay that when I first saw it i thought of the movie. (An excuse to throw an IP into the park)
EDIT: Actually now I think about, if it was an IP based on one of films then it's either based on a forgotten film from the early 70s or a total failure of a remake so perhaps that is unlikely. Maybe I just thought too quickly!
Doesn't have to be an IP. Using the Wicker Man film as an IP is a bad idea, because it is supposed to be a horror movie. With it near a family area like Mutiny Bay, it would be a bad place to put it. I know Th13teen is a horror themed coaster, and that's pretty close to CCL, but there's nothing scary about it from the outside, whereas a large wicker man could be scary to some people, if it was actually based on the film.
It could be based on the burning man festival (seen below), which someone might have already suggested, because they could create a large festival type area, and have something slightly darker to do with the large wicker man/burning man in the middle.
Or, it could just not be a wicker man at all
