In Final Fantasy XV you can eat chocobo. Maybe they say what it tastes like in there. Haven’t played it.
I think @Seek gave a great answer on the subject though. We also have to consider the type of chocobo. If you eat a white chocobo from Final Fantasy IV, maybe you gain some temporary magical properties. Since they don’t seem to travel much, perhaps there is a lot of dark meat in those. However if that world has any laws, you’re probably not allowed to kill them as they seem quite rare.
The fat chocobos from the same world aren’t probably any good as they just sit around all day, plus dwarves seem to value them highly. But what are those dwarves going to do about it, since scrap the tanks! There won’t be another war! I wonder how you say that in Khuzdul.
Black chocobo wings are probably the best part since they fly around, and can go round the world in like seven seconds.
Would the red chocobos from Final Fantasy Tactics be spicy, since they use fire attacks? Spicy red chocobo at the sports tavern while you watch your dueling competitions!
