Well... that's not completely the case. It's implied real animals exist in the Pokemon world. But of course there will be Pokemon that could be eaten...
...I'd eat a Spheal.
In episode 57 (the one where the gang goes to Cinnabar) Ash (or maybe it was Misty) exclaims "I'm so hungry I could eat a horsea."
It made me chuckle.
Haha, well I guess you have a point there but I still find the whole concept slightly bizarre.Well you see, there seems to be more Pokemon than actual animals, people have got to eat some thing I guess :P
I remember seeing a fried chicken stand in one of the Johto episodes (I think it was 'Grin to Win'). That was before the Torchic family was revealed.
