Sonja is now at Sans and Papyrus' house, lying on the coach. Sans comes in bring in soap.

"I brought you some soup. in case you're hungry." Sonja smiled as she takes the soup.

"Thanks, Sans." Sonja gives a kiss on Sans' cheek which his face turned blue. Papyrus comes in with a wet rag and places it on Sonja's forehead.

"REST UP OKAY? THE GREAT PAPYRUS AND MY BROTHER WILL NURSE YOU BACK TO HEALTH!" Sonja smiles as her eyes went wide and throws down the rag as she transforms into a Mermaid, shocking Sans and Papyrus. 

"Sorry, guys...It happens when I touch water." Sonja pulls down her cover revealing her scaly turquoise top.

"whoa..." Sans walks to Sonja, feeling her tail.

"SANS CAN I FEEL IT TOO?" Sans nods as Papyrus feels Sonja's mermaid tail.

"IT'S SLIMY!" Sonja chuckles.

"Sometimes when I was at the sea, I used kelp to keep my tail nice and shiny." Sans and Papyrus looked at each other.

"WOWIE..." Sonja smiles as the bubbles engulfed her, transforming back into a human.

"I gotta say you look beautiful as a mermaid." Sonja blushes.

"Thanks, Sans." she covers her body.

"Get some sleep okay?" Sonja nodded as she closes her eyes and rested on the coach.

"THAT GIRL IS REALLY SOMETHING." said Papyrus.

"I agree but...she's beautiful..." Sans blushes in deep blue.

"SANS, DO YOU HAVE A CRUSH ON HER?" asked Papyrus.

"N-N-No I don't!" Sans covers his face with his hood.

"DON'T HIDE IT FROM ME BROTHER, YOU CAN TELL ME." Sans sighs.

"Yes, I do...." Sans confessed as Papyrus gasps.

"Y-YOU HAVE A CRUSH ON A MERMAID?!" Sans nodded.

"WOWIE! YOU HAVE TO TELL HER!" Papyrus shouted.

"but bro, what if she doesn't like me. she's not like any monster in the underground." Papyrus rubs Sans' head.

"OH, SANS...I KNOW SHE FEELS THE SAME WAY. JUST TALK TO HER TOMORROW OR MAYBE BRING HER TO GRILLBY'S IF SHE'S FEELING BETTER." said Papyrus.

"that sounds like a good idea, pap." Papyrus smiles. Sans yawns.

"welp, I guess I'm heading to bed. it's getting late." Papyrus walks upstairs.

"WE SHOULD REST UP. SANS, CAN YOU READ ME THE BEDTIME STORY PLEASE?" asked Papyrus.

"sure, bro. I'll be up." said Sans as he walks upstairs. 

At Papyrus' bedroom, Sans has a book saying, "Peek-A-Boo with Fluffy Bunny" and he opens up the book.

"alright, ready pap?" asked Sans.

"YES, SANS." Papyrus is wearing orange pajamas, snuggling with a teddy bear.

"alright, once upon a time......."

Sans read the bedtime story to Papyrus and Sonja is outside of Papyrus' room, listening to it which she smiles before heading downstairs heading back to sleep.

(Here's Chapter 7. I hope you like it and I don't own anything.)
