While his chest grew fur and his ears swelled up even more, David got a big surprise as his thumbs grew claws and his other fingers stretched out. They stretched and stretched, with each bone loroking thinner as his knuckles spread apart. Each hand seemed destined to outgrow his whole body!
Then the skin between them also started stretching, until each hand looked like a giant leathery sail. It got weirder when the same kind of skin started connecting his thumbs to his shoulders and his pinkies to his feet, so that his whole arm was just embedded into the sail. It felt freakish, and it was freaking him out.
"What is wrong with me? Why am I changing into a bat? who would have known I was thinking that?" he wondered as his tail grew out and even more webbing connected it to his legs.
Within seconds, He now looked like one giant wing with a little furry body in the middle and a head sticking out. He was a bat!
