House of Weird/ House of Parallel Universes (mild Suite Life crossover)
Chapter 1.
"Ok, so we send Nina this package, and Arwin's science group this one?" Zack Martian ask his brother, Cody. The twins were about to mail their cousin a gift for boarding school, a big box of cookies, not made by their mom, a giant teddy bear, and a bean bag chair.
"No, no, no. Not unless we want Nina in a parallel universe!" Cody told him, "Remember when that happened to us?" the two shivered at the memory.
"Ok... But she did steal all my gummy worms that one summer..." Zack muttered.
"Are you ever going to get over that?" ask Cody, "You were 10, she was 7, seriously?"

LATER AT ANUBIS HOUSE

All the kids were in their rooms fast asleep when Nina's gift arrived, but Victor was wide awake. He opened the package, which Zack had failed to put Nina's name on, in his office and saw... Parts to a machine? And blue prints! Blue prints to build a new and improved P.U. "What's that, and why did someone send it to me?" he though.t After further observations, he found out it was a parallel universalizer, and for Nina. "Well Corbiar, I believe I will have the elixir in another world." Then he took it to the attic and started his work.

LATER THAT WEEK in Nina's POV

I was sitting in the attic about to have a Sibuna meeting, Amber and Fabian were already there, we were just waiting and the others. It was a little dark in one corner, but I noticed an odd shape. "Fabian, is it just me, or is there a phone booth over there?" I ask "Whoa! What's that doing there?" he ask "I don't know..." I said as I walked over to investigate.
"That's really creepy Nina! I wouldn't go touch it if I were you!" Amber warned "I'll be fine, what if it has something to do with another mystery!" Over the past few weeks, we had been searching for a new mystery constantly, so far nothing. "WHOA!" I yelled as I tripped into the creation, little did I know I had activated it. I soon found myself trapped in there, with colors flying and spinning all over the place. "Let me out!" I screamed, that was dumb idea. NO ONE WAS HERE! Then it stopped. I was back in the cellar, back with... Where was everybody? A girl with blond, straightened hair came in. Amber, i realized, but something was different. She had a sports team shirt on that read Millington, 04, baggy jean, and a pair of grey tennis shoes.
"Who are you?" she ask.
"I'm Nina. Your roommate?" Amber looked at me blankly, at least that was normal "Amber! I know you remember me!"
"My roommate? I don't have a roommate! My old roommate moved in with another girl, after her's moved away! And how do you know my name?" Joy moved away, that was normal too, except that Joy had come back for the next school year.
"New student! They showed me pictures of who everyone was!" I said, remembering my first day, and not getting to know who everyone was.
"Ok, well you said you'll be rooming with me, right?" She ask, "Well come on! I'll show you where it is!" She dragged me off to our room.
When we got there, it was completely transformed. Apparently, this Amber loved sports. Posters of all sorts of ball players covered her half of the room, she had a sports comforter set, and a soccer ball bean bag. She all also had a track suit out to put on, and a pair of shoes in a better condition then the ones she had on. "Whoa..." was all I could say.
"Pretty cool, right?" She said, gesturing to her half of the room. "I can help you set up your stuff later! Need the exercise! I'll lift all the heavy stuff!" She offered That was all I got to to hear, because then everything went black...
