"So, young man. I know juat tge way to get rid of you." Mr. Grindler injected Riley with a syringe.
Riley started screaming as he noticed his skin droop. Ecebtually it stopped at his hips. Teh skin then attached to his body and little bones came in. Balck furspreades along.
"You have been a very bat boy! Haha!"
Riley started to feel lumps on the top of his head and then felt his ears disappear. Riley was deaft but only for a moment as little black ears popped out of riley's head.
Riley freaked as his nails became sharp claws and reduced into small webbed paws.
Riley was human in his mid body, dick and legs (though shorter) as well as his face (save for ears). Everything else was bat.
"Fly away, go!"
A sobbing Riley fkew away.
