On Five Island go to the left, towards the water and use Surf. From there travel up and when you see an opening to the left turn in there and keep going, find your way around the rocks until you find a small patch of land. You'll see a girl and an Old man. Talk to the old man, I can't remember if he challenges you or not, but if you have a spare slot in your party, he'll give you an egg. In that egg is Togepi, to evolve Togepi, I think it evolves by friendliness, so once it adores you, raise its level and it should evolve. Note: I think the first pokemon in your party must adore you before he gives it to you. Hope I helped ^_^
PS: I haven't done it in a while so I'm not 100% sure. But that doesn't mean I didn't get it right...
Feiry sees you.
