Seriously, how can we consider that a secret animal when we can't adopt it by normal means in the game? To me a secret animal is one you unlock by finishing the whole game for example. Like the Triceratops and Unicorn in the first game, those were considered secret animals until you finished the scenerios to unlock them. So should we consider the other "mistake" animals that we create besides the KP secret animals also? Since they are created the same way as the KP might as well, huh?
