Greasy Lil Non Playable Ratapotamusaurus 

A name for Liam Ferrera, an obese, greasy non playable character in real life. It is said to be a human but more closely resembles a humanoid hippopotamus. He bathes in grease, and ultimately, can shoot loads of grease from his you know what. Fun fact! His brain is half robotic and you know what powers it? His grease! He produces grease that fast food restaurants leech his grease off him. His shirts are too small for him, so there's your answer as to why you can see his belly. He is a deep sleeper. Call him and he will not flinch. He also has a thing for legs, so be weary of that, as he can get incredibly close to you (he doesn't know what personal space is.) He will do anything to look under your dress/skirt. If you want a boy who knows about Pokemon, you're in luck! He is the right person for you. He will blow your mind away with how much he knows! Unfortunately, he isn't a memorable person. Well... to some, he is. But not in a good way.

who is that? why is he looking at her legs?
oh! it's liam ferrera (known as the greasy lil non playable ratapotamusaurus), don't bother. he can't get close to girls, so thats his next option.
