My reaction would be something along the lines of, "Thanks, what do I do with it?" Seriously, what would I do with a Pikachu? There aren't any other Pokemon so unless I go around killing other people's pets, I can't really have any 'battles' with other people, I can't really train it since almost nothing lives wild around here (which just leaves me with the pet murder thing). And turning it over to scientists is definitely out cause, well,
I couldn't let them experiment on that.
