There are actually four variations of this pet, not three.  There's two white ones, one being slightly larger that the rest.  It's not as significant a size difference as, say, the Temple Snake appearances, but it's noticeable if you compare them side by side with a friend.

There are two display IDs for this pet, 2957 and 35802.  They're the same coloration, but 2957 is significantly bigger than the other.
