"Ummm...." being put on the spot, you don't really know what you want, or even if you want it. Why not try it on someone else? You hate to do this, but you have three wishes, right? You can always try and fix whatever mistake you end up making. "I wish you'd transform my roommate, Jack," you say to the genie.
"Into what, master?" The genie retorts. You think for a second, unable to come to a decisive answer.
"He's a furry, just uh...make him into some kind of anthro animal or something...idk just suprise me.
The genie grins at you, "As you wish, Master." He claps his hands twice and instantly he's gone in a puff of smoke. Excited you rush home to your apartment. As you come to the door you hear a tv playing loudly on the other side. You unlock the door and come inside to see a large figure sitting on the couch watching the tv. It hears your enter and turns around and staring back at you isn't the Jack you knew.
