I always find this monster a bit odd, I mean, out of it's 4 heads it has, why is one of them a goat included?
Shouldn't it be another carnivore animal?? What does an herbivore can do anyway?
The scariest thing I can thing of is:
"GuaHahahaha! Be careful of my goat head! It will eat your homework!"
Quite lame, right? So, really, why does it have to be a goat??
