What's going on?!

A/N: So I wanted to do something with Joker, and then I thought "Hey he's a thief, mischievous, and cocky. This is good material..." So this idea is now here. This is an image of Joker's final smash so.... Credits to Sakurai.

I woke up to an arubt screaming. 

Since the scream startled me I fell out of my bed head first upon the floor. 

I quickly put on my shoes and changed the rest of my clothes and ran out of my room to the source of the screaming.

"What happened?!" I yelled across the hallway. 

Peach was on the floor with Daisy and Rosie. She was clearly sobbing too.
 
"Somebody stole my crown!" She exclaimed upset.

"Stole? Like a thief?" I inquired.

"Yeah! Somebody stole my tennis racket too!" Daisy chimed in.

"Along with my favorite book that I read to the Luma's." Rosalina replied a hint of sadness in her voice.

"Don't worry! I'll let Master Hand and Crazy Hand know and we'll get back your items!" I responded confidently.

I ran downstairs to the Hand's office's. I knocked quickly.

"Come in!" I heard Master Hand said.
I entered in out of breathe and began to explain to Master Hand what had happened.

"So what you're saying is that... There's a thief in the mansion." Master Hand summarized. 

"Yes, and I believe they are still out there, possibly stealing other's items." I responded quickly.

At this Master Hand had pushed a little button. "Attention Smashers, please be careful today and make sure you have all of your belongings. There is a thief around Smash Mansion. We will try to solve the problem soon." 

"So what do we do?" I asked as soon as he was done with his announcement. 

"Like I said, be careful make sure you have all of your belongings in a safe place." He replied.

"Gotcha. Thank you Master Hand." I said as I left his office. 

While I was walking back upstairs, a thought occurred in my head. What if that thief stole something from me?

With this idea now in my head, I ran up the large staircase.

Once I had made it I entered in my room and looked around. Everything seemed to be in place... Wait a minute....

"WHERE'S MY NECKLACE?!" I screamed. (It's the same necklace (S/C) got you for your birthday.)

"(Y/N)! Did the theif steal something from you?!" Roy exclaimed from your doorway.

I groaned loudly in annoyance. "I can't believe this!" I yelled.

"Don't worry (Y/N), we'll find the culprit soon." Robin reassured.

"I hope so..." I said quietly. "Have you guys lost anything yet?" 

"Yeah, I lost my bandana!" Roy whined. (The one that he usually wear on his hair)

"And I also lost some of my tomes." Robin replied. 

"I just hope this gets resolved soon. How's the other smashers taking it?" I inquired.

"Er... Not the best." The tactician said.
I looked out into the hallway to see a bunch of the others just running around frantically.

"I'm gonna try and find this theif." I told Roy and Robin.

"Then how about we'll go with you?" Roy offered.

I smiled. "Sure, but hurry because the hallway is packed."
