Creature Teacher (Goosebumps Series 2000, #3)

Mrs. Maaargh stepped out from behind the desk. Her bare feet made wet, smacking sounds on the carpet. She began to circle me, her brown eyes studying me hungrily.

Her stomach growled. So loud, I jumped. It sounded like the gurgle of a bathtub emptying.

"You can't do this!" I gasped, "It isn't...human!"

That made her smile grow wider. "I'm not human," my new teacher said. "I'm a monster."
