Avm Magic Park Escape

A new type of predator has appeared and took over the food chain. No other species could stop them from spreading all over the area. They're the fiercest and most aggressive species we've ever seen in these lands. If they keep spreading like this, the whole park will be endangered. We need to intervene and stop them. I'm open to any suggestion on the matter. How should we start and where? In my opinion we should find their nest and get rid of them. Good luck and hurry up!
