You knock on the door to the stall.
"Dad? Are you in there?" you call out. You hear a rustling noise and hear a voice cry out. "Dad? I'm scared, please open up..."
Still more rustling comes from the stall, but no response. You push on the door repeatedly until the lock gives and the door is forced open. You were not prepared for the sight that greeted you. Your dad's body was covered in coarse brown hairs. His skin was black and leathery, matching his large wings. His ears were points and his face had reformed, becoming a melding of human and bat, yet somehow you still recognized him.
You slowly backed away from the stall, trying to process what happened.
