Riddle
Yikes
It eats
It moans
It kills
It groans
It makes snacks out of any living creature
It is made by dying
It could be your teacher
It could be your sibling
It stalks during the night
It stalks during the day
It has a one-track mind: food
When its around, you better not stay
Its Dead
But its Not
It fills people with Dread
It eats people a lot
What is it?
