>>28630497Exotic animal meat and non-food pokemon probably have a lot of similarites: a unique quality, but rarely very good eating. Animals that aren't cared for and fed a specific diet will likely have a gamey taste. I'd be even more careful eating plant pokemon than I would terrestrial plants, as a lot of those Grass-types have toxic, soporific, or paralytic spores. I'm not even sure many of them are even fully plants.
This is discounting pokemon that are outright poisonous, incorporeal, immortal, or made out of inorganic material.
