There are a lot of strange things in the world but one of them shouldn't be the frogs. I grew up camping. In a family with nine kids, that's the way we spent our vacations. Of course looking back, now, I realize it might have been relaxing for Dad but Mom was working her tail-end off. Just think of packing for eleven people. And campsites weren't well-equipped back when I was growing up. We even had to haul in our own water.
But back to my point. We used to spend hours catching frogs. It was our own catch and release program - before I'd ever heard of such a thing. But I never found one freaky frog. According to National Geographic Freaky Frogs are the norm.
It sounds like a scary movie to me: Freaky Frogs.
