Gahana
A Gahana looks like a bird, but it's got the temper of a feral cat on a sugar high. If you stare at it, it'll scream, kick you in the crotch, and probably throw up on your shoes.
My Gahana woke up and yelled at me for eating its cereal. I’m not even sure it had cereal.
I saw a Gahana in the park, and it started crying and kicking a pigeon. I left before it got violent.
My neighbor’s Gahana tried to eat my dog. I had to call the cops and a therapist.
