Horse (like the one the player starts on at the very beginning)
That’s all I can think of. There’s only so much you can do with a farm because most of the other zones have taken possible farm animals.
Also, I think your abilities for animals should be varied a bit, because your cows are pretty much identical to sheep, your donkeys are pretty much identical to giraffes and your turkeys are pretty much identical to emus. Like with Islands, I think you should attempt to come up with some new, refreshing behaviours.
Also, when making a blog for the Sinnoh region, just keep in mind that Sinnoh is the fourth region of Pokémon, featured in Diamond, Pearl and Platinum. You have to include Sinnoh Pokémon or at least Pokémon from those games, not others.
