A furry monster that's originally the size of your fist but can morph into greater sizes up to that of a car. Nobody is sure of it's gender. It is rather aggressive and has been sighted recently roaming the outskirts of Paraguay hunting homeless dogs. It is rumored to be related to "el chupicabra" but it is known to repeatedly hump the students and teachers in nearby school facilities after excruciating math lessons.
"Dude, I will be traumatized for life. I think I just ran into Fabris in the hallway and it looked at me. It scared the shit out of me!"
