Markimoo

An unusually hyperactive and adorable animal that needs to be taken extreme care of. It is mostly known for its funny antics and prettiness. But beware as it can shout at a considerable volume on being raged and can start weeping over anything that is even remotely emotional. It can be mostly found with it's friends in the wilderness; just be careful of hurting it's massive ego or it will bite ya.

Friend: "Hey, what is that ?"
Me: "Oh that, thats just a wild Markimoo in it's natural habitat."
Friend: "But why is it running around with peanut butter on it's face ?"
Me: "Shh...We don't question anything."
