She is a pretty pokemon. Having her live inside you isn't that bad. You were about to take a nap under a nearby tree until a thought crossed your mind. "I'm glad you enjoy it in there" you tell her, "but how do I get you out?" "That's simple" she replies, "You can gag and vomit me out soon, but if you don't, it'll be too late if you know what I mean. I don't mind either way since you drank from the lake. I'll come out either way you like. Besides" she giggles, "I don't really have a choice now do I?"
