I can't remember if there was a pokemon based off of a chicken. There's one of a cow, why not a chicken haha! I honestly wouldn't see the significance in it though since we can't eat them or have them fly us anywhere.
lol, i'm just saying random stuff
Umm torchic lol
i think lama dolphin and of course flamingo and i would also like to see another shark pokemon a bit more like a lil baby shark getting bigger and ending up looking like jaws, i would mind seeing a squirrel again pachi was a bit of a letdown or possible an evolve. A panda or polar bear would be good possible a swan as the resident flying pokemon like pidgeot and a falcon with these too possible female male counterparts, and a real gorilla wolves and am Aussie so i have to say kangaroo and platypus just by law
i could go on but i have to go to dinner
Forgot to mention more extinct pokemon like dinosaurs and what not
