You are a female lugia. Never mind the canonical issues. You are overflying a coastline area idly looking for something to do because today has really been rather boring. It is a beautiful, sunny morning, and your eyes are sweeping the area below you. You overfly a forest and see a beach and a pokemon on that beach. It looks to be a very small pokemon, a Rattata on further inspection. Perhaps you could swoop down and introduce yourself?
