Crossover time again~! I'll try my best to update this more, I know i'm not good with chapter stories...at all. But, this time i'll try! Alright -takes out list- Nothing belongs to me...Story inspired by the movie Equestria girls and Disney...yada yada, blahblahblah. -throws list away- enjoy~!

This is a story about not what happens when Twilight is forced to go to a human world, but a world completely different.

My crown was stolen by Sunset Shimmers, I must get it back! Princess Celestia said that the world I will be going to is odd and dangerous and I must be cautious. I will do just that, I know nothing about this world or the people in it. Well, nothing too bad will happen...right?

Twilight Sparkle went through the looking glass, to get back her crown, with Spike following after her. As Twilight was being sucked into the world, she felt her body go through changes, many changes that made her uncomfortable. Suddenly, she was thrown into the world, all she could hear was the sound of rain. She slowly woke up to see she was on a sidewalk, her head was splitting with a headache. She held it tightly, she tried to look around but her vision was blurry. She suddenly heard a familiar voice. "Twilight?" It asked. She looked up to see a purple and green bat. "S-Spike!? You aren't suppose to- wait...are you a...bat?" Twilight questioned. Spike took a quick look at himself and nodded. "I think so. Twilight! You're a mouse!" He yelled, surprised. "Oh Spike~" She said as she got on her knees. "You're being rid-" She was interrupted as she turned around, seeing her reflection in what looks to be a store window. She truly was a mouse. A purple mouse with the same hairstyle as she had before and big purple ears. She was also wearing a white and purple victorian dress as well as a white choker and black, high heeled shoes. Her eyes widen as she just looked at the reflection, speechless, but after a few minutes she made a noise...a scream.

"AAAAAAAAAAAAAHHHHHHHHHHHHHHHHHH!" She screamed. She then quickly covered her mouth. She pulled on her ears, her tail, her fingers, and looking around at her new body. She then began hyperventilating. "Twilight! Pull yourself together!" Spike told her. She did just that, taking deep breathes. She looked at the reflection again and hugged herself. "T-this is insane..." She said. "Why would Sunset Shimmer want to be here...of all places." She asked. "Maybe there's something we aren't seeing." Spike said. "You're right, we can't worry too much about this. What's done is done and we have to get the crown asap." Twilight said, trying to build her confidence. "But, in such a large place like this, we're going to need some help." She said, suddenly a newspaper flew to Spike's leg. He picked it up and began reading the article, Twilight didn't notice. "Someone very smart, who's found such valuable things before and succeeded. But who...?" She asked herself. "How about Basil of Baker Street?" Spike suggested. "Who?" She questioned, turning back to Spike. "Apparently this guy's 'The Great Mouse Detective'." He said, still looking at the article. Twilight slowly took it from him and began reading the article herself.

"Great Mouse Detective solves yet another case..." Her words trailed off as she was reading out loud. She read the rest of the article in her head, after reading it all, she smiled wide. "He's perfect~! He's just the guy we need!" She exclaimed. "But I don't know where this 'Baker Street' is..." She said. "We have to come across it eventually." Spike said. "You're right Spike, we better hurry though, I don't want to be stuck as a rodent longer than I have to." She said. She was about to trot away, like she would in her pony form but Spike quickly grabbed her foot. "What?" Twilight turned to Spike, who still had her foot. "I don't think you move around like that." He said. "What makes you think that?" She then pointed out, Twilight looked in that direction to see a female mouse and what looks like her son, were walking on their feet. "Oh." She tried to get on her feet and almost fell over, but thanks to Spike she didn't. She tried to walks but fell against a light pole. She sighed and hit her head against the pole in annoyance. "This...is going to be harder than I thought." She said, sighing.

After what felt like an eternity of wobbling around the streets, she finally reached the last home to check before she'd go find somewhere to sleep. She rubbed her eyes, tired and looked at the address. "221..." She read out loud. She then let out a long yawn and stretched. "Alright...let's hope this is it before I pass out." She said. Spike nodded in agreement, feeling tired himself. She knocked on the door and after a few moments a somewhat large, female mouse answered the door. "Yes, may I help you?" She asked. "I hate to trouble you at this hour miss but, would this happen to be the home of Basil of Baker Street?" She asked. "Yes it is but, he's not here at the moment. He should be back soon so please come and make yourselves at home." She offered, opening the door more and moving out of the way so they can walk inside. Both Twilight and Spike smiled wide, quickly walking in the house. Twilight looked around the room to see books and different sorts of experiments going around.

"Woaah..." She whispered to herself, staring in awe. "What's your name, dear?" The woman asked. "Oh, I'm Twilight, nice to meet you." Twilight introduced herself. "And this is my friend Spike." She said, pointing to Spike who was looking around the place. "Oh, it's been raining so much, you two must be chilled to the bone." The Woman said. "Here, you both sit and relax while I go bring a pot of tea and some fresh cheese crumpets." She said. "Thank you, we apperciate it~" Twilight thanked as she watched the woman walk to what seemed like a kitchen. Spike sat down in a chair as Twilight looked around the room. She couldn't help but look closely at the experiments. She then quickly noticed the large supply of books. She quickly ran to them, looking at them with awe. "I wonder what kind of books he has.." Twilight said to herself, she took a large, green book and began reading it. "Twilight, do you think it's a good idea to be snooping through this guy's books like that?" Spike questioned. Twilight sighed. "You're right Spike, besides, I can't be getting off topic. I just hope this Basil guy comes soon." She said, putting the book away.

After what had seem like an hour, the door opened to reveal a male mouse wearing some sort of detective outfit. "Ah, Finally. The rain has been picking up." He said, taking off his coat. The female mouse from before came to the door and closed it. "Good evening Ms. Judson." He greeted, putting his wet cloak in her arms as he walked off. Ms. Judson sighed, putting his coat on the coat rack. "Mr. Basil, you have guests." She said, in an annoyed tone. "Oh?" Basil raised an eyebrow and looked to see Twilight sitting on the chair. She got up and waved. "Hi, my name is Twi-" She was interrupted by a gasp as Basil quickly ran by her, making Twilight fall on her bottom. She looked to see that he was making a mixture of sorts. "Hmm...Looks like i'll need more..." He said to himself. He placed down his experiment and looked back at Twilight who was on the ground. He walked up to her. "My apologies Ms." He said, holding out a hand for her. Twilight hesitantly placed her hand on top of his as she was helped up. "Twilight." She introduced herself. "And over there is my friend Spike." She said, pointing to him.

Basil looked at him, confused. "Odd, I don't find many bats nowadays..." He said, looking closely at Spike. "W-well, we're not from here. Anyway, I need your help." She said, with her hands behind her back. "Oh, of course. Basil of Baker Street, at your service. Now what seems to be the trouble?" He asked. "Well, you see...I was walking around town when...something was stolen from me. A crown." She answered. Basil raised an eyebrow. "A crown?" He repeated. "Yes. I know it sounds odd but it belongs to someone VERY important to me and I need your help to find it!" She said. "Of course, I just need you to explain what the thief looked like and what your crown looks like as well." He said. "Well, I didn't get a good look...but I noticed bright yellow and red hair, as well as light red fur." She explained the look of Sunset Shimmer. "Hmmm, how peculiar. Now the crown."

"Oh, right. Well it's a golden tiara with sapphire gems and on top is a large magenta, star-shaped diamond." She explained. "Ah, seems to be the basic thief case. They probably think that crown is worth millions~" Basil said, smirking. "Ms. Twilight. I accept your case, your crown will be found soon and your thief shall be brought to justice!" He said, with a lot of confidence. Twilight smiled wide and couldn't help but hug Basil, tightly. "Oh Thank you! Thank you! You have no idea how much this means to me!" She thanked, still hugging him. Basil felt his cheeks turn a bit warm as he slowly pushed her away from the hug. "Well, yes. I promise, I will find it." He said.

Little did they all know, someone was watching them through the window. All what could be seen was a pair of light, bright blue eyes. "Twilight Sparkle! You will pay for stepping a hoof here!"

CLIFFHANGEEEEEEEEEER! MWAHAHA~! I know i'm evil, and before you ask, this will have some Basil x Twilight shipping moments in it. I'm surprised no one else ships them! Like...really!

Anyway, hopefully chapter two will come soon. Thanks for reading~
