Jeff thought about what to try, and finally settled on a bird. He'd love to be able to fly, see everything from a new perspective. He just couldn't decide what kind of bird.
He ran though the random settings, making sure to set it to "Avian" and thought about the time. He'd want more than a few days, but not too long. He eventually settled on a week. He took care to make sure the doors to his room and house were open, since there was a chance that he'd be turned into a bird right there, and he'd have to get out somehow.
He stood in front of the emitter and hit the enter button. Unsurprisingly, his clothes vanished and a moment later the room dissolved around him. It was replaced with... a barnyard?
He looked around even as he felt his body changing. "Oh crap!" He managed to say, "I'm going to be a --BWAK!--"
He felt the world get larger as his body started to sprout large, brown feathers. Instead of majestic wings like an eagle, his arms reformed into meaty chicken wings only good for short hops. He felt his teeth melt away, reforming into a beak that pushed outward in a strange pushing sensation that ended after a few minutes.
Jeff stood, shocked, in the middle of the yard. He was going to be a chicken for the entire week?!
