AN: Thanks for the reviews, and please keep them coming! Yeah, frankly, I have no clue what Matryoshka is about either. I just like the song. I really like the Halloween Vocaloid songs, so this chapter is Trick and Treat, and I'll probably do Mrs. Pumpkin's Comical Dream, too. If anybody has any ideas of songs to do, send them in and I may write them in a chapter!

2. Trick and Treat

"Come on, we promise, it'll be super fun!" The boy on the right said. His twin, the girl on the left nodded enthusiastically at the green twin-tailed girl in front of them.

"Yes, yes, really, really super fun!"

"A Halloween party? Aren't those for little kids, though?" The green one repeated, as if to verify that she wasn't hearing things. "Will there be other people there, too?"

"Of course, Miku, its a party! Parties have people!" The girl said, leaving Miku to wonder how she knew her name. "I'm Rin, and this is Len. Follow us, we'll show you to the party!" Len grabbed Miku's hand and they all took off down a dirt path curving with the shape of the forest.

"You guys look so familiar," Miku said, all nervousness in her voice leeching away. There was something calming about these two, something that made her want to go to this party more than anything she had ever done.

"Familiar?" Len said with a smile. "Not at all. We've never seen you until now! See, our parents told us to go into town and see if we can make any friends to invite to the Halloween party."

"We throw the best parties!" Rin added on. "Apple bobbing, scary decorations..." Rin trailed off as a large house came into view. Crafted out of gray stone, it looked almost castle-like. One window in a large room towards the left of the house had a stained-glass window, but Miku couldn't make out the design from so far away.

"This is a gorgeous house," Miku complimented just as Len's grip on her hand tightened. Rin opened the heavy looking door with an old key as she said, "Too bad we live here alone."

Miku's heart started beating faster, her pupils shrinking to pinpoints. "What-alone? You said that you had parents that-"

"Yes," Len said sadly. "had parents...We loved our mother very much, but then she threw us away."

Miku figured this was some sort of metaphor, not realizing how literal the small blonde boy was being. "Wh-where are all the other people?" Miku gasped as she was pulled inside. The house was empty of people, but filled with a huge variety of furniture from all different eras.

"We couldn't find any other friends." Rin said, with the same sorrow tone as her brother. "You're our only friend, Miku."

"I think...I think I should be going now, my mother will be looking for me," Miku said, trying to worm away. Both of Len's hands clasped hers now, and he gazed up at her, insisting, "We must show you the house before you leave. Every guest gets to see the whole house."

"O...Okay..." Miku followed Rin and Len nervously up the stairwell.

"This is my favorite room in the whole house," Rin said, a certain creepiness entering her tone.

"How did you know my name?" Miku asked suddenly.

"We know all about you, Mother. Everything there is to know!" Rin giggled.

"Mother...? Ahh!" Miku let out a squeal as the twins began to transform in front of her. Lines and joints, fading paint...they were now life-size dolls.

"Come see it, Mother!" Len pulled her into the room. Miku now knew why they seemed so familiar. They were the dolls she had thrown away a few years ago. The room was empty except for one long shelf. On the shelf were three dolls, with pink, blue, and purple hair.

"You threw us away, Mother," Rin whispered, locking the door behind her as she entered the Doll Room.

"I-You were just dolls! I didn't think that you were alive, or that you had feelings, or-oh! This must just all be a crazy dream!" Miku screeched, pressing the palms of her hands against her ears.

"It will be soon." Len said slowly. After that, everything went silent.

Later

"I can't wait for you to be our friend! Let us show you our favorite room!" Len giggled, leading the next girl up the stairs. She was also green-haired, but was wearing odd red goggles on her head.

"Ohh, okay, I guess...But after this, I really should be heading back home, my mother will be mad I've even been gone this long," Gumi said, trying to be kind to these lonely-looking twins.

"Don't worry, it won't take too long," Rin said reassuringly with a smile. "You're going to be our best friend, I bet! We used to have another friend, but she left..."

They entered a room up the stairs, at the end of a hallway. It was empty for all but one shelf. There were four dolls, a mature looking one with pink hair, a shocked looking one with blue hair, a purple haired one dressed like a samurai, and a small one with green twin pigtails.
