When I was watching Dawko put in the codes to see the teaser photos, there was this picture of a lab. I can tell it's a lab because of the test tubes and microscope. There was also a screen nearby, that is a scan of a bird. The specimen encased in the container might be an egg, presumably from the bird, and that bird might not be Mollie Macaw because of the minor difference on the beak. But that bird might be the animal "base" they used for Mollie, and the scientists are going to mutate the genes of the egg to make the mascot.

I think we might get some flashback scenes, and this is probably how Mollie is created. When she got decapitated, there was blood all over the place, so this means that these mascots may not be animatronics. They might contain the genes of their real life counterparts, or maybe the officials in the park got the animals then mutated them.

I think Salem may be an anti hero, by the way, because maybe they want to free the mascots via corruption, or the indigo park company got sued for animal experimentation, leading to its closedown.
