This animal isn't around to be petted or kicked, or to assist in taking over the world... well, it might be, but only as a side job. The real purpose of these animals is that of most motifs: they're there to underline a theme, or make a statement about a certain character. They might not even be physically present at all. The "animal" might be the name of a football team, a charm on a bracelet, or an ornament on the mantelpiece.
