Chapter 6: Spooky, But Harmless (P, W.D., S, F)

Frisk tried to sit up, but she was so tired from being pushed around by the bullies who had pushed her down into a hole she had found. She had landed not too long after she had fallen, but she was a bit bruised and sore. She then closed her eyes.

Something brushed some of her hair from her face and she opened her eyes to see a skeleton looming over her. She then realized she couldn't move and found both her arms and legs in casts and tried to move. "Child, stop squirming," said the skeleton as he gently held her shoulders down and saw her face filled with fear. "Shh," he said, sitting down beside her. "Relax. Take a breath."

Frisk swallowed and took a deep breath. "Good girl," he said. "You're already under a bit of stress. You don't need more of it."

She looked at him. "What do you mean? Who are you? Where am I?" She asked.

"You have a few broken bones," said the skeleton. "Two in each of your arms and one in each of your legs."

Frisk looked upset at that and saw the skeleton had holes in the palms of his hands and gasped. He gave her a curious look and then chuckled. "Oh, my hands," he said. "An accident from long ago."

He then ruffled her hair. "To answer your other questions, I'm Dr. Gaster and you are in my lab in my brothers' and my home," he said.

Frisk began shivering and he noticed. "You don't need to be scared of me or my brothers, little one," he said, but he saw that she was still a bit scared. Her stomach then growled. "Oh, that reminds me. You suffered some severe bruising on your stomach to the point that your stomach can't handle anything but liquids for a bit."

Frisk looked surprised. "How badly am I hurt?" She asked.

"You'll be healing for a while, but you'll survive, little one," he said. "By the way, what is your name?"

"Frisk," she said before her stomach growled again. Gaster smiled a little before sighing lightly.

"I hope you don't object to my feeding you," he said. "I'd rather not place a feeding tube in you."

Frisk shuddered a little. "You wouldn't do that. Would you?" She asked.

"If you had stayed unconscious any longer, probably," he admitted. "You were unconscious for almost two days."

The young girl looked surprised and then saw him set down something on the table nearby before sitting down beside her, adjusting the hospital-like bed so that she was sitting up before feeding her what she recognized to be tomato soup. She then realized something.

"Um, how did I get here?" She asked.

Gaster chuckled. "My brother, Sans, found you," he said. "He got you to me after you fell down the hole leading to here."

Frisk gasped. "You're a monster!" She exclaimed in horror.

Gaster flinched at her cry and saw she renewed her struggling despite the casts weighing her down and the pain she was in from struggling. "Frisk, please," he said, easily grabbing her and pinning her down. "You're badly injured."

She began shaking and started to cry. Gaster lifted her up gently, being mindful of the casts, and held her, rocking her gently, holding her head gently against his shoulder. "Shh," he said. "Calm down, little one."

Frisk hiccupped a bit and felt Gaster rub her back, which helped her to calm down a bit more and she looked up at him as he gazed down at her. "Are you…a monster?" She asked timidly now.

Gaster sighed. "Yes, I am," he admitted.

Frisk looked confused. "But…you haven't scared me or hurt me," she said.

Gaster chuckled a little. "Because I prefer not to," he said as he gently laid her back down on the bed. "Now, how about you finish your soup and get some more rest?"

"But I'm not that tired," Frisk protested as Gaster picked up the bowl of soup and resumed feeding her. He chuckled as he continued feeding her. When she finished the soup, he set the bowl aside and smiled at her.

"Better?" He asked.

She nodded. "I guess I was hungrier than I realized," she admitted before giggling when Gaster patted her stomach, to his surprise.

"Oh, your stomach is sensitive, I see," he said with a chuckle.

Frisk looked a bit afraid at that, but Gaster chuckled again. "I'll wait until you're fully recovered before giving you a tickle torture," he said, ruffling her hair.

Just then, someone teleported right near them, making Frisk jump and Gaster sighed. "Sans, I thought I said to knock," he said.

"Then knock, knock," said the blue-hoodie wearing skeleton that just appeared.

Gaster sighed again, but smiled a little and Frisk giggled. "Who's there?" She asked.

Sans looked at the human in surprise, but then grinned. "You," he said.

"You who?" Frisk asked, a bit curious as she hadn't heard that one before.

"You've got my attention, kid," he said with a grin.

Frisk gave it some thought before she began giggling as she got the joke. "You're funny," she said.

"Just my bone-fide nature, kid," Sans said, giving her a friendly wink, making Frisk giggle again and Gaster smiled this time.

"At least you didn't make her afraid as I did," he said.

Sans looked at his older brother. "Why would she be afraid of you, bro?" He asked in confusion. "You're the one who's helping her get better. You fixed her up after I found her."

"But you know how humans have heard about us monsters down here," Gaster said.

Frisk looked at them. "I don't think a monster would help someone who is hurt or tell jokes," she said.

Sans grinned widened. "I like you already, kid," he said, reaching over and gently tickling her chin, making her giggle. "I bet Pap would like you instantly too."

"Pap?" Frisk asked.

"Our youngest brother," Gaster explained as he saw Frisk yawn. "You can meet him later, after you get some more sleep."

"But…," Frisk started to protest when gentle fingers rested on her mouth in a gesture of 'shh'.

"Gaster's right, kid," said Sans. "You need some more rest for your body to recover."

He pulled something out of his pocket and placed it by her shoulder. It was a stuffed monkey and she smiled. "Figured that might cheer you up a bit," the shorter skeleton said with a chuckle as Gaster pressed the nearby button to lower the head of the bed back down and then tucked the covers around Frisk.

"Sleep well, little one," said Gaster, gently pinching her cheek as he and Sans watched her fall asleep.

Frisk woke up the next morning to see Gaster sitting beside her. "Good morning, Frisk," he said with a smile. "Feeling better?"

Frisk's stomach growled loudly, making him chuckle and her giggle a bit. "Guess I'm a little hungry," she admitted.

Gaster chuckled. "First off, let me get your arm casts off," he said.

"My arms healed already?" She asked.

He nodded and removed the casts and she tested her arms and found she could move them. "Your legs will be healed in probably a couple of days," he said as he picked her up and began carrying her out of his lab and down some stairs into the kitchen. A skeleton almost as tall as Gaster was at the stove making French Toast and turned to greet them.

"Good morning, brother!"

"Good morning, Papyrus," said Gaster.

Papyrus then saw Frisk. "Hello, Frisk!" He greeted enthusiastically. "Sans and Gaster told me all about you. The Great Papyrus is glad to see you are doing better!"

Frisk couldn't help smiling and instantly liking Papyrus, who set down the spatula in his hand and gently took Frisk from his older brother, giving her a big, gentle hug before carrying her over to the table and placing her in one of the chairs. "Breakfast is almost ready," he said with a smile. "I bet you're hungry."

Frisk's stomach growled again and she looked a little bashful. "I guess so," she said, making Papyrus and Gaster chuckle at her shyness as Papyrus ruffled her hair and went back to making breakfast while Gaster went to look for Sans, finding him asleep on the couch.

Frisk jumped when she heard a shriek of surprise from the living room and Papyrus also jumped, but then laughter filled the house right then. "GAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHSTER! BRO! COME ON! AHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA! STOHOHOHOHOHOHOHOHOHOOHOHOHOHOHOHOHOHOHOP! AHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA!" Sans laughed out.

Papyrus laughed. "Get him, Gaster!" He called out.

Frisk laughed a bit. "What is going on?" She asked.

"Oh, Gaster is simply encouraging our lazybones brother to wake up," said the cheerful skeleton. "My second oldest brother is very ticklish and it sounds like Gaster went for Sans' weakest spot: his ribs."

The young girl laughed a bit more. "Are you and Gaster ticklish too? Or just Sans?" She asked.

Papyrus looked a bit stunned and she grinned. "Guess that's my answer," she said.

The tall skeleton's face when from stunned to sly as he came over to her. "Gaster happened to mention you having a very ticklish tummy," he said as his hands rested on Frisk's stomach and his fingers lightly wiggled into her ticklish spot, making her giggle a bit, but then Papyrus stopped. "When your legs are properly healed, I'll give you the best tickle torture you've ever experienced."

Frisk laughed. "I better make sure I can run fast then," she said.

"No one escapes the Great Papyrus!" He said playfully, making her laugh some more.

Gaster came in, carrying a winded Sans on his back. Frisk giggled as she watched them and Sans grinned at her. "Hey, kiddo. Feeling better?" He asked.

She nodded and then looked at Gaster. "Gaster, you said I was badly injured," she said. "So, how did my arms heal so fast?"

"The medicine I gave you was a powerful one that works fast to heal injuries," Gaster answered. "Another dose or two of it should heal the rest of your injuries."

After breakfast, Papyrus followed Gaster back to the lab, carrying Frisk and setting her down on her bed again, watching as his older brother gave the girl a shot in the arm of the medicine he spoke of earlier. Before Frisk knew it, the day had flown by and she was sleepy again. This time, when Gaster tucked her in, she felt the three skeletons kiss her forehead before she fell asleep.

Gaster had done some research on Frisk and found out she was an orphan and with Sans' help, was able to gain the adoption papers necessary and filled them out, adopting Frisk as his daughter. "She's gonna flip out when we tell her you adopted her," said Sans.

"I bet she'd plow us over in her joy," Gaster said with a smile.

Papyrus was too excited over the fact that he now had a niece to groan at his brothers' puns. They soon went to the lab where Frisk was still resting and Gaster quickly did some x-rays and found Frisk's legs had healed and he nodded. "Her legs casts can come off," he said.

Sans gently shook Frisk's shoulder and she woke up. "Good morning, sleepyhead," he said.

"Morning, lazybones," she said.

Sans laughed and ruffled her hair. "You must have slept well to be that sassy this early in the morning," he said teasingly.

"Yeah, I slept pretty deep," she said with an enormous grin.

Gaster got the pun right away as did Papyrus, who groaned. Sans took a minute before he got the pun too. "You're a natural, kiddo," he said. "No one's ever gotten me stumped on a pun before."

She giggled. "So, what's up?" She asked.

"Well, your legs casts can come off," said Gaster. "And we have news for you too."

Frisk looked worried. "Is it good news?" She asked.

The three skeletons looked at each other in surprise. "Well, we'd like to think so, kiddo," said Sans.

"It's no doubt the best news you've ever received," Papyrus said, grinning hugely in an attempt to make Frisk smile. She smiled a little, but didn't say anything as Gaster removed the leg casts and then sat down, pulling Frisk into his lap while Sans and Papyrus sat near them. Frisk still didn't look happy until Gaster gently squeezed her shoulder.

"Frisk…I've adopted you…as my daughter," he said.

She looked up at him, stunned. "What?" She asked.

"I found out that you were in an orphanage and adopted you," he said.

Frisk was absolutely stunned and completely still. "Frisk?" Papyrus asked worriedly.

"Kiddo, are…?" Sans started to ask.

Before he could finish, Frisk had suddenly tackled Gaster, making him fall back on the bed as she hugged him. Chuckling, the tall skeleton hugged her back and watched her tackle his younger brothers and hug them. They returned her hugs happily.

"Thank you," she said softly. "But, why would you want to adopt me so fast?"

Sans and Papyrus grinned and watched as Gaster lifted Frisk back into his lap and tickled her chin playfully. "We've been watching over you for almost a week, little one," he said. "You practically became part of the family the first day when Sans brought you down here."

"My older brothers have a huge soft spot for children," Papyrus said with a smile, making his older brothers both laugh and Frisk snuggled into her new father's arms.

"Now then, didn't Papyrus and I promise you something when you were better?" Gaster asked, his smile growing.

Frisk knew what they meant and was about to escape when suddenly both Gaster and Papyrus were caught up in Sans' telekinesis. "I've got them, kiddo," he said with a grin.

The young girl laughed and quickly ran off before the shorter skeleton released his brothers, who gave him playful glares that told him he was in for a tickle torture too, but he teleported away, finding Frisk in the living room. "Come on, kiddo," he said. "They'll be here in a moment."

Frisk followed him and Sans had just teleported them to his room when suddenly, they were both encased in Gaster's arms. "Nice try, Sans," he said.

The next couple hours were filled with laughter as Papyrus held Frisk and watched Gaster tickle Sans before the oldest skeleton let up his younger brother, who exhaustedly rested his head on his older brother's shoulder and Gaster set him down on the bed to rest while he and Papyrus turned their attention to Frisk.

Frisk was soon wheezing for air as her new father and uncle tickled her good and then Gaster held her in his arms, holding her in a fatherly way.

Frisk leaned her head on his shoulder as she hugged him. Because of these three skeletons, who she at first thought were spooky but now saw them as harmless, she had a home, something she had wanted for a long time.

I just had too. :)
