Free Body Switchers from Outer Space by R.L. Stine

stole my body, and I want it back!”
    â€œI did not steal it!” Chad croaked. “You gave it to me!”
    â€œChad-One! How could you?” Chad-Two shouted.
    â€œI want to stay here,” Chad said.
    â€œYou want to what?” Chad-Two was so shocked he squeaked. “You would destroy everything we’ve worked on for two years local time just so you can stay on this stupid planet?” Chad-Two fumed. “You idiot! You fleeflaw! You groober!”
    â€œWill you help us switch back?” I asked.
    Chad-Two’s face was purple. For a minute his mouth just opened and closed and no words came out.
    Then he blinked a couple of times. His eyes narrowed. He looked really mean. “Oh, yeah. I’ll switch you back. And then it’s mind-tailoring for you, Chad-One!”
    â€œFine,” I said. I was afraid of Chad-Two. But one thing at a time. First I would get my body back, then figure out what to do next. “Pepper, you stay here.”
    â€œOh, no,” Chad-Two said. “The larva comes with us!”
    â€œLarva?” Pepper shrieked.
    He glared at her and she shut up.
    Chad groaned again.
    â€œWhat’s wrong with him?”
    â€œI gave him a pinch of pinter,” I explained.
    â€œPinter? In an Earth body? He needs some sklix right away!”
    â€œAfter we switch,” I said.
    â€œOkay,” he agreed. “How did you plan to get him back to the storage module?”
    â€œOn my bike,” I said. I pulled the lifter out of my pocket and tapped it up to size. “Will this work on him?”
    â€œGood thinking,” he said. Then he remembered who he was talking to and glared at me.
    We lifted Chad to his feet. He leaned on me and I raised his shirt. Chad-Two put the clear ball against Chad’s back. And lifted him with no problem.
    We left the driveway, me on Chad’s right, Chad-Two on his left, Pepper walking beside me.
    I sneaked a peek at my watch. Quarter to two!
    When we reached the house, we rushed over to the silver puffball mushroom shed out back. I opened it with the touch pad.
    â€œWow!” Pepper said, staring at the door opening. When we stepped over the threshold, she said wow about fifteen times—every time she looked in a different direction.
    Chad-Two went over to the touch-pad console and pushed the pad that opened the change chamber doors.
    The familiar, sour smell wafted out.
    I took Chad over to one of the big, purple telephone booth change chambers and settled him inside, then tapped the lifter so it let go of him.
    I tapped the lifter small. I shoved the lifter and the merister into Chad’s pockets—my own jeans pockets—then went and climbed into the other chamber.
    â€œReady?” asked Chad-Two.
    â€œReady,” I answered.
    A second later the doors whooshed shut and I was in the dark again.
    It was all just like before.
    I felt as if I were jerking sideways on a carnival ride.
    But when I opened my eyes again, boy, did I feel different!
    I felt hot and then cold. My stomach ached. My throat hurt. I could feel sweat pouring off me and soaking into my shirt.
    My mouth felt weird. I ran my tongue on the backs of my teeth. Braces!
    They were mine! Will’s!
    Oh, man! I never thought I would be so glad to go back to being Will the Spill!
    The door whooshed open.
    Pepper ran over to me. “Will? Are you okay? Are you— you?”
    â€œYour birthday is May eleventh,” I gasped. My throat hurt as the words came out. “Your favorite color is red. It worked, Pep. Thanks for believing in me.” Then I moaned. My muscles were burning!
    Pinter! The pinter I gave Chad while he was in my body was still having an effect. It was making me sick!
    I glanced around for Chad-Two. He was opening a cabinet in the wall.
    Chad-One stormed out of the other change chamber. He looked furious. “I hate you, Will Kennedy!”
    Chad-Two came over with a small blue box. He tapped it up,
