I understand the appeal. I really do. But you probably don't even need me to tell you that, for the most part, animals don't make noises for our entertainment. Right in the description of the video, the guy who filmed this refers to what you're hearing as a "defensive cry." Nothing cries out in defense when it's content. That this frog is repeatedly calling for help means someone is most likely prodding it in some way. That would explain why the camera starts moving once the frog stops making noises. Something has to be done to make it start squeaking again, and sticking a camera in its face did the trick the first time.
"Dance, frog ... DANCE!"
It's also worth noting that this is a nocturnal animal that wants nothing more in life at that moment than to be burrowed 20 centimeters below ground and resting peacefully.
Still, it wouldn't be that big of a deal if it was a one-time thing, I guess. It's not. The man who filmed the video, Dean Boshoff, also cranked out a sequel a few months later.
