one mythical creature could be a jackalope! also I think the game needs to add all the animals that are in the spectator stands in the sports games, I have seen a penguin, a bulldog, a godzilla/lizard, a rhino, and other dogs and cats that are are already in the game but just not playable. I also have noticed animals that are in the trailer that are not in the game, so hopefully they are soon to be added!
