Everyone here says that the Honeying pet is the cutest. I absolutely have to disagree!
Keblings are the CUTEST!
I love the way they lean forward and put their arms up like they are saying, "booooo" and trying to scare you.
But yeah, I am with the rest of them, one for each of your chars is probably enough.
I have the cute kitties marraige pet, honeying, kebling, and slime.
Since the marraige pets have better stats I will never change it off of my main but the rest of them swap around.
