I'm a monster who looks like a blonde maiden in a hot pink dress that is twice your height.
You just watched me feed a man a poison apple. When he keeled over, I opened my mouth and out came a large snake-like creature with sharp teeth that devoured him in one CHOMP. I then spat out his bones from a green monster head under my dress into a hole in the ground.
I then notice you, not realizing you witnessed me do all of that. I then approach you.
"Oh, a weary traveler... I could only imagine how hungry you might be after traveling this far."
I pull out an apple from my basket and offer it to you.
"Here. Have this apple. You best eat it now considering what's ahead."
I stand there waiting for you to eat it, trying to hide my wicked glee as I watch you.
