[Oh, hello again. It seems the kid's taken his suggestion to get a Porygon; they are quite useful after all!]

Indeed they are. I haven't raised one myself, but my training partner has. I've fought against it several times and I can assure you that it's an incredibly powerful Pokémon. I've actually hatched the Swinub eggs to make sure they came with the correct moves, so you won't have to worry about hatching them.
