Guild pet level error?

From what my Pyraurus, Pyurode, and Gerikygo look like, they should be in their final forms, and they haven't changed forms in awhile. But I keep on checking back, and they are still leveling up and don't have their final form yet. Is there some final form that we don't know about, or is this an error?

Sorry, it is meant to do that because when I eventually add a battle system for the guild pets that means they are at their full power, though they still look the same. I guess I probably should add some kind of medal to show their final stage since it is a lot of leveling... I just have so much to do already. >.<

Ok. Take your time with it if it isn't urgent.
