I got Pokemon moon and chose Litten as my starter. Named her Sheyenne and in the game, when you choose the pokemon, it comes a ceremony to see, if the pokemon you choose is liking you as well. In my head, it's a bit more funny. As I try to choose one of the three pokemon by pointing it, the litten jumps in and bites on my arm, and the professor is happy, that it choosed me as her trainer.
