Then Justin got an idea. He took Bills body and pulled on it. With a pop his pelvis and legs separated from his body which he took to Jeff's body and positioned it just where the head would have been. Jeff's and Bill's heads of course were ripped of their plastic bodies before and watched the whole thing from a distance. "I think he's got some plan", said Bill to Jeff. To everyone's surprise Bill's body snapped into Jeff's with a click.
Then Justin pulled Bill's arms and put them down, replacing them with Jeff's legs. Adjusting the stance, he moved them forward so Bill's previous back was now horizontal and had 4 legs with an additional body sticking more or less straight up at its front.
"So... who wants to be a centaur", Justin asked his friends and Jeff answered, "Well it sure beats being a disembodied head. Sign me up". Justin picked up Jeff's head and pushed it into his torso. In a flash the centaur sprung into life and stretched his plastic limbs, "Much better".
"What about me", cried Bill. "Don't worry I've gotcha", said Justin. There still was a pelvis and 2 arms left over so he connected them to each other. Then he picked up the remaining head and pushed it onto the pelvis. "Thanks, though I think I've got the short straw".
