Danny plays with the buttons and then wanting to see what the ray feels like, he points to himself and pulls the trigger.
Immediately a sense of vertigo washes over him and everything grows bigger. It was about then that he notice that he could feel a cool breeze against his legs and that his crotch felt really weird.
Looking down he sees his pants and underwear piled up around his feet and his shirt has grown several sizes. Stopping himself in mid thought, he realizes that he has shrunk. Lifting up his shirt as the sensation in his crotch grows, he has just enough time to watch it and his testicles finish shrinking and then fold back up into his body.
Then all of a sudden the area splits and the clitoris, clitoris hood, urethra, vagina form and then are covered by the Labia Major and minor.
Gasping in realization, he now see that this ray gun has turned him into a eight year old girl.
"I have to find my sister and now." She says out loud, noticing that her voice has also shifted upward to match the body that she now inhabits.
