Mystery of The Ardbark Demon

You start to play around with your belly, the more you do it the more it hurts. Eventually, the baby kicks so hard that you cry out in pain. Then suddenly your water breaks on your sister's bed. Your best friend Josh enters the room your in and is shocked of what he is seeing.
"Your pregnant!?!"
"JOSH! You scared me."
"How did you..."
"Window."
"What?"
"Don't ask."
"Ok. Also, I'm GIVING BIRTH!"
"OMG!"
He runs over to you and helps you deliver the new born baby. When you look at your new child, it reminds you have your younger sister.
Josh says.
"Where is your sister?"
"I have no idea."
He looks at the new born and says.
"We have to get out of here. To my house."
"Why?"
"You'll see, just come on."
You follow him to his house. You and him sneak the baby into his room. When you close the door you look at Josh.
"What is going."
"Do you know what the Ardbark Demon is?"
