The World's Happiest Animal

I found this video about an animal called the Quokka. It's a cute little Australian animal that always looks like it's smiling, and people are going crazy about it taking selfies with it. I think it's an interesting video, so here it is. I never heard of this animal before. I wonder if my local zoo has one. I hope all this attention doesn't kill the poor animals. I hope they have some kind of a protection plan for them because often when people go crazy about animals like this, it doesn't have a good effect on them. Often they go extinct if people bother them too much.
