Based on some Smurfs and Undertale fanfics.
"Oh boy, I love when it's with this windy climmate!!!" Belle said, putting her trench coat.
"The best things are what we are going to do tonight, Bell!" Jazzey said.
"I am wondering what can we do first..." Belle said.
"We could watch some movies." Jazzey said.
Both girls ate some marshmallows until they were full and were sleepy and tired of watching movies.
"So, are you excited for Easter, sis?" Jazzey said.
"Yes, can't wait for it to came!!!" Belle said.
Jazzey was sleeping, when she heard her sister talking in her sleep.
"LET ME GO!!!" Jazzey said.
Jazzey entered on Belle's bedroom.
"Belle, what's going on?" Jazzey said.
Belle shouted, but felt it was Jazzey.
"Oh Jazzey, I had a dream where a voice was saying 'You can't escape, I will haunt and kill everyone on Halloween Town!!!'" Belle said.
"Go back to sleep, maybe you are only scared because dad told about the story of the rivalry he had with Oogie Boogie." Jazzey said.
"Say whatever you want, Jazzey! But tbis can be a premonition, and I'm speaking seriously!!!" Belle shouted.
"Why are you two discussing?" Sally said
"Belle just had a bad dream." Jazzey said.
"I think it was a premonition!!!" Belle said.
"Premonition? Of what?" Sally said.
"I don't know, I only heard a voice on my dream. I think it's because the story daddy told me scared me a little bit. I'm going to drink some water..." Belle said.
"Want me to turn on the lights for you, Bella?" Sally said.
"No." Belle said.
"If you need anything, talk with me." Sally said.
When Belle finished drinking her water, a giant vine was outside.
"Hey! Open the door!!!!" A voice called.
"Who is outside there?" Belle said.
"Open the door and see by yourself." The voice said.
"I'm blind, but I still can hear you. Who are you?" Belle said.
"YOUR FINAL DESTINY." The voice said. A vine grabbed Belle by her waist.
Belle screamed, being caught by vines.
"LEMME GO!!!" Belle yelled.
"HELP ME!!! MOM!!! DAD!!! JAZZ!!! HELP ME!!! SOMEONE HELP ME!!!" Belle shouted.
The creature put Belle on the ground, the vines holding Belle tightly on the floor, where a red star with black candles were.
"Let's begin." Someone said.
"BELLE!!! WHAT HAPPENED?!" Jazzey screamed, seeing the scene.
"GET HER TOO!!!" The voice of Oogie Boogie yelled to the black demon with hands and legs in forms of vines, eho caught Jazzey.
Jazzey was being holded on the air, being squished by the vines.
"Can't...breathe...help..." Jazzey weakly said.
"MOM!!! DAD!!! WE NEED YOUR HELP!!!" Belle called.
The parents of Jazzey and Belle appeared, seeing that their daughters were on danger.
"OOGIE BOOGIE!!! LET THEM GO!!!" Jack shouted.
"No way!!!" Oogie shouted.
A red aura appeared on Belle's eyes and body, burning the vines.
The vines of Jazzey burn.
Jazzey screamed while falling.
"I DON'T WANNA DIEEEEEE!!!!!"
Jack caught Jazzey on his arms.
"You are secure now, Jazzy." Sally said.
"Papa, mama, what is happening to Belle?!" Jazzey said.
"Her body is full of a red light!!!" Sally said.
"I never saw that going on with Belle!!!" Jack said.
"LEAVE EVERYONE FROM THIS WORLD ALONE, OOGIE BOOGIE!!!" Belle yelled.
Belle threw a explosion that made the demons and Oogie Boogie disappear.
Belle eyes came back to normal.
"I feel so dizzy..." Belle said, fainting.
"Belle!!!" Her parents shouted, running to her.
This is what Belle heard before passing out.
Belle felt a hand caressing her hand and something wet on her head.
"My whole body is burning and is hurting." Belle said weakly, feeling pain over all her body.
"Hush dear, you are going to be okay." Jack said, putting a compress on Belle's forehead.
Sally was taking care of Jazzey, who didn't got hurt like Belle, but was worried with her big sister.
"My back is full of pain..." Belle said.
"Shush, you are going to be fine." Jack said, making a massage on Belle's back.
"Daddy, what happened to Oogie Boogie?" Belle said.
"Sweetie, you defeated him, for real." Jack said.
"A red aura exploded out of your body burning Oogie and the creatures that were hurting you and Jazz." Sally said.
"Dad, are you proud of me?" Belle said.
"Belle, I always be proud of you like your mom. You and Jazzey are my two princesses." Jack said.
"I'm so tired...Good night." Belle said, closing her eyes.
"Good night, my sweetheart." Jack whispered, hugging Belle and kissing her on her forehead.
