Well, it exists in my world, sort of, but it’s apparently split into various branches.

Being an Animagus allows you to turn into animals, I have known of some people who can do that. Meanwhile, there is actually an ability to talk to snakes and that is very uncommon in my world. I once had it due to some weird incident in my life before, which explains how I was able to understand the snake in the zoo, but not anymore.
