THANK YOU FOR REVIEWING! :D :D :D It makes me happy.

So I was thinking, Christmas prank war or Christmas alien attack? Then I thought, why not both? After all, an invasion by hostile aliens on Christmas is practically mandatory by now for Earth. :D :D :D :D :D Oh, and a cookie if you caught all the references!

Christmas had only just started, and so The Doctor, Jack, and Martha went downstairs, Martha sipping coffee from her enchanted mug, to go to breakfast. They had sat down, and everyone was in bright spirits. They opened Christmas crackers (Much more fun when magic!) and then IT started. The Doctor had just drunk some of his pumpkin juice.

He turned into a wallaby.

Silence fell over the Great Hall. Then laughter burst out from near the door. The three friends turned slowly, and The Master was doubled over, cackling. He was covered in neon pink splatters of dye. The Doctor grinned, which was hard for a wallaby. "It worked!" He then bounded over the table and hopped towards The Master yelling. "YAAAAAHHHH!" "AAAAHHHHHH!" The Master shrieked and ran away. Martha and Jack looked at each other, then shrugged. "SPARTAAAAAA!" They yelled as they ran after them, wands brandished.

"…Sparta?" Professor McGonagall said after five minutes of stunned silence. Then the teachers shrugged and continued partying.

Outside, there was a massive battle going on. The Master and The Doctor were dueling, The Master as a llama and The Doctor as a wallaby. Martha and Jack weren't quite sure how the llama happened, but… whatever. After a duel, a rap battle, and a dance-off, The Doctor and The Master turned back into Ron and Yana. Martha and Jack were still getting over the fact that a wallaby and a llama had a dance-off as The Master (still pink from the dye) went back to the castle to grade papers. When The Doctor turned back to his friends, they were laughing their heads off and recounting some of the more epic dance moves.

Suddenly the sky darkened. The friends fell quiet and looked up, just in time to see an enormous spaceship with what looked like a bird painted on the underside fall onto the meadow. "D'arvit!" was all The Doctor said. Jack looked at him oddly. Then the spaceship opened up and all three of them swore as aliens with poured out. Literally poured; they seemed to be blobs made of some semi-liquid viscous substance. "I'm not sure about this reality, but I might have blown up their planet," The Doctor muttered to himself. Martha stepped on his foot. "Shush! They might be peaceful!" The two boys looked at her disbelievingly, then looked back at the lead blob, who was doing something involving humming and flashes of light. The Doctor swore vehemently in German.

"They're going to nuke the planet!" he cried. Martha and Jack took action. They, in unison, shot stunning spells at the spaceship-which bounced off. The blobs seemed to be angry at this, as they began to turn orange and pouring themselves towards the three. "Don't let them touch you!" The Doctor cried. "Their snot is highly corrosive! Augamenti!" Water burst from his wand, dousing the blobs, who began turning runny. Martha and Jack caught on and cast the same spell, driving the blobs back. The Doctor ended his spell and aimed his wand upwards. "Vade!" The spaceship disappeared.

The blobs were runny but still dangerous, as they now oozed towards the three friends. "RUN!" yelled The Doctor. And so they all did what seemed to comprise of a lot of their adventures-ran for their lives. When they dared to glance back they saw that, indeed, the trail the blobs left was bubbling and orange and eating into the ground. "This way!" The Doctor yelled. They followed him as he ran straight towards the lake. At the last minute they jumped aside, but the blobs overshot and fell into the lake. They hissed and steamed, and eventually dissolved into nothing. "What-what were those?" Martha asked as she gasped for breath. "Merfolk food, now." The Doctor replied. "Quite tasty if your digestive tract can handle it," he added. They all collapsed into fits of giggles.

Suddenly Jack stood up. "Doctor?" "Hmm, yes?" "There are angry teachers coming towards us." The Doctor looked. "Why, so there are. And The Master is laughing his head off. You know what I think we should do now?" "What?" Jack and Martha asked together. "Run."

They were shrieking with laughter as they ran back to the castle.

:D I hope you enjoyed! Review if you caught all the references.
