A/N: This is something I've had in my head for a while. I know, it sounds odd that I could have something like this in my head for a while, but it has occurred to me a lot recently, so I want to get it out there. Enjoy!
"When you said this planet would keep us on our toes, I didn't think you meant it literally!" cried Amy as she and the Doctor ran back to the safety of the TARDIS. "Well, Pond, you should have actually listened to what I said next. I also said that there were wild, carnivorous aliens in this forest!" the Doctor replied. As they entered the TARDIS, a red light lit up on the console. The Doctor ran to the console to try and find out what the problem was, while Amy was trying to stop the door from barging open to reveal what would be a race called the Cravians. "Doctor!" shouted a very angry and tired Amy. "Yes?" replied the Doctor, not looking at Amy, which meant he was unaware of what she was doing. "Take the TARDIS off, I can't hold this door much longer!" said Amy. That was when the Doctor realised what was happening. He turned to look at Amy and saw she was struggling to keep the door shut. He started to run around the TARDIS console, twisting dials and pulling levers, and the TARDIS roared into life.
When the door stopped shaking, Amy assumed that is was safe to leave the door. She walked up to the Doctor and asked him something that he had completely forgotten about. "Doctor, what was the red light for on the console?" The Doctor stopped in his tracks and turned to look at Amy. "I forgot about that. I'll just check." And with that, he looked at the screen and saw what the light was for. "There is a problem that needs assistance immediately. Don't touch anything while I'm fixing it. You can go down to the pool for a while if you like." the Doctor said as he turned to go to the lower console area to fix the TARDIS.
Amy walked into the swimming pool, put on her bikini and swam around for a while. When she got out, she ran to her room, and when she had finished getting changed, she heard a noise come from the bathroom. She cautiously opened the door to find a creature that was chasing them earlier staring at her. "DOCTOR!" shouted Amy at the very top of her lungs.
"DOCTOR!" The Doctor looked up from what he was doing, dropped everything and ran out of the control room. He ran into Amy's room to see the creature cornering her. "Leave her alone!" demanded the Doctor. The Cravian turned to face the Doctor. It let out an unearthly scream. Amy cowered in the corner, while the Doctor reached into his pocket to retrieve his sonic screwdriver. He threw the screwdriver to Amy. "Amy, setting 1042-B, quickly, aim it at the Cravian." Amy had no idea what he was on about, but did it how she interpreted it. But she didn't manage it in time. The creature took a bite out of her arm. Then the creature ran over to the Doctor and took a little bite out of his arm. By this point, Amy had started to feel queasy, and seconds after the Cravian had bitten the Doctor, he felt queasy too. The Doctor stumbled over to where the sonic screwdriver was and clumsily picked it up. He aimed it at the Cravian and pressed the activation button. The Cravian screamed and hollered and eventually disintegrated. Amy collapsed on the floor, unconscious. The Doctor had just managed to put the sonic away when all of a sudden, he collapsed too.
The Doctor was the first to wake up. He quickly jumped to his feet, feeling rather different. He looked around to try and find Amy, but all he saw was himself laying there. "Am I dead?" he thought to himself. All of a sudden, he saw his body climb off of the floor and stand on its own two legs. His body look at him and his eyes widened. The Doctor looked down at himself, looked up, and suddenly looked back down again. He was wearing a miniskirt, a red t-shirt and no shoes. "What's happened?" he asked himself, and then he noticed something. His voice had a Scottish accent, and it sounded rather like... "I'm in Amy's body!" he shouted to himself and what he realised must have been Amy, who was looking down at her new body with... a smile on her face! "What's so funny, Amy?" he asked with Amy's voice. Amy realised that she had been caught glancing at the Doctor's body, and looked up, blushing. "What happened, Doctor?" asked Amy with her manly voice. "Well, it's obvious that we have switched bodies, but I still don't know what you find funny about being in my body." said the Doctor, furiously. "It's just... nothing." said Amy sheepishly. "Well, we have to go back to Cravania to find out if there's a cure there." the Doctor said, but as he was about to dash off to the control room, Amy stopped him. "Wait there." Amy said, and she walked over to the corner of the room and picked up her brown boots that resembled cowboy boots. "Put these on first." said Amy. "Why?" asked the Doctor. "Because you're not wearing any shoes." said Amy. The Doctor looked down at his feet and sure enough, he was bare foot. "Oh, ok." said the Doctor, so he put Amy's boots on, and ran out of her bedroom.
When the Doctor reached the control room, he immediately started to pilot the TARDIS back to Cravania, but he found it harder than he normally would since Amy's boots didn't provide much grip on the glass floor.
The city on Cravania was beautiful. It had silver trees, blue grass that smelt like strawberries, and the streets weren't like what you would normally see in any other city. They were very quiet, with the occasional transportation vehicle here and there. It was very peaceful. Until the TARDIS landed. The Doctor ran out of the TARDIS and scanned the block for a science lab. He found one on the other side of the road. He made sure there were no vehicles heading towards him, and he darted across the street. Amy followed after him, struggling to keep up in the Doctor's body. Normally, it would be her struggling to keep up with the Doctor's body, but even now she was in the Doctor's body, she was still struggling to keep up with her own body. Amy eventually caught up with the Doctor on the top floor of the building, where it seemed he had been up there for 10 minutes, as there was a scientist mixing up 2 identical potions, one for her and one for the Doctor. "How did you get him to make the potions without bribing him?" asked Amy. "Well, Pond, it seems that I have your habit for flirting, either that or your body's controlling me in a certain way, but I have to tell you, I had to make a deal with him. He thought you were pretty hot, and he wanted to do some stuff with you. I won't go into any further detail, but I said yes, and now you've got to do it later. Sorry." said the Doctor smugly, rather enjoying the look on Amy's face, which was actually his face. "Doctor, I would slap you now, but I'm in your body and I don't want to hurt my own body." said Amy, obviously furious with him. "Amy," he whispered in her ear, "I only said that because he could hear me. As soon as we have switched back, we're going to make a run for it, got it?" said the Doctor. "Oh, ok, sorry Doctor." said Amy, feeling upset and guilty for shouting at the Doctor like that.
"While we're waiting for the potions, can I ask you something?" said the Doctor. "Sure, fire away." said Amy. "Just after we had switched bodies, when I caught you looking at me, why were you smiling. It's like you were happy to be in my body. Why were you smiling?" asked the Doctor. Amy froze. Should she tell him, or make up an excuse. She went for the former, because she couldn't hide it any longer. "Doctor, I've never told you this before, but I love you, more than a friend. I'm surprised you haven't picked up on that yet. I've been giving you loads of clues." explained Amy. The Doctor sat there, dumbfounded. Amy loved him. He couldn't believe it. He thought that it was just him loving her more than a friend. He was secretly glad to be in her body, and it took every ounce of him to stop himself from inspecting her more than just the clothing. "Amy, I love you too." said the Doctor, and they both leaned in for a kiss. As soon as their lips touched, they felt a tingling sensation go through their bodies. When they pulled away, they had switched back to their respective bodies. "I'm done, stay there, I'll inject this into you and you'll switch bodies." said the scientist. "NO!" shouted the Doctor and Amy simultaneously. But it was too late. They felt a tingling sensation run through their bodies again and when they looked down at themselves, they were back in each other's bodies. "Oh well," said the Doctor in Amy's voice, "at least we can spend a lot of time with each other." But the scientist noticed the change in behaviour, and injected them again, and now they were back inside their correct bodies. "It feels better to be me again." said a very relieved Time Lord. "Me too." said a very relieved human. Now the scientist stepped in. "Now, miss, I believe we have something to do together?" said the scientist seductively. Amy looked at the Doctor, and the Doctor looked at Amy, they both looked into each other's eyes and, hand in hand, they ran off. The scientist ran after them, and as he got outside the building, he saw the door of a blue box close, but not before seeing a ginger haired woman peek around the door.
The Doctor ran to the console and Amy followed him, the TARDIS showed Amy a few of the different controls so that she could help the Doctor as he was very weak and tired. They both reached the Time/Space Throttle together and, together, they pulled the lever down and watched the time rotor move up and down. The scientist stood amazed as the TARDIS dematerialised right in front of him. But Amy and the Doctor didn't know. They were too busy locking lips to look at the screen and see his dumbfounded face staring at the TARDIS. Together, they would have a wonderful relationship.
A/N: A bit cheesy towards the ending, don't you think? Sorry, but it was the only thing that sounded ok in my head. Please review. It will make my day.
