To becompletely honest I never saw the resemblance until it was brought up here, but now I can't UNsee it. Just like Castform and Magmar. I doubt it was intentional, but at the same time I keep hearing fart noises in it and Skuntank's cries... so maybe? I'd rather not think it was, because that is pretty low. Digimon has enough toilet humour, I don't need any in my Pokémon, thanks.
