Dying (part 3)

So here’s how it happened. One day I was at home when I got a frantic call from my friends. They were both at Ophelia’s house, and something strange had happened. Green slime covered the floor and her parents were gone. Then I heard her scream and I lost connection.
I ran outside and got on my bike. When I got to her house I saw a faint green glow coming from the windows. I ran inside, and upstairs.
“Ope-” Then I saw. Green monsters were surrounding her. I pulled out my knife, and sliced them in half. “Guys, please explain.” I said.
“Isabella, look out!” Ophelia screamed as she jumped behind me.
I turned around just as I saw a Green Monster swallow her whole.”Ophelia!” I screamed as I killed the monster.
But it was too late.
