The next morning, Toriel and Sans were going out, so The others had to care for Frisk.
"Ok, I'm officially stumped," Alphys said, trying to stop Frisk from crying.
"Well, she can't be hungry, we just fed her three plates of spaghetti!" Papyrus said, trying to make funny faces at Frisk.
"Ugh! Would you two stop, you're upsetting her more!" said Undyne, the one who was holding Frisk.
"Wait, maybe she needs, burping?" Alphys said, looking at Undyne.
"Ugh, fine! I don't really get babies," Undyne said, patting Frisk's back. Soon, Frisk stopped crying, let out loud burp, and giggled. Undyne laughed. "I guess that's all she needed," she said, setting Frisk down. Frisk got on her hands and knees and started crawling towards Papyrus. When she got to him, she reached up to him and giggled.
"Oh, hello tiny human," Papyrus said, picking her up. Frisk giggled and started messing with Papyrus's scarf. "You're silly, you know that?" Papyrus said, booping her nose. Frisk giggled. "You're laugh is silly, do you want to hear mine?" Papyrus asked. With that, he let out a crazed laugh. Frisk laugh at this.
"Alphys, have you found out a way to fix her yet?" Flowey asked Alphys, in an annoyed tone.
"I'm working on it Flowey, but I think Frisk is kinda cute this way," Alphys said.
"Well I don't," Flowey remarked, folding his leaf like arms. Papyrus kept on finding new ways to make Frisk laugh, until Frisk wouldn't laugh anymore.
"What's wrong tiny human, do you not have any more giggles?" Papyrus asked the child, trying to make her laugh. Frisk didn't show her face, she kept on looking at the floor trying to avoid eye contact with anyone. It wasn't until Undyne caught a glimpse of what looked like tears streaming down Frisk's cheeks, she spoke up.
"Now look what you Papyrus, now she's crying!" Undyne said, face palming.
"Oh tiny human, I'm sorry if I upset you," Papyrus said. Out of all of them, Flowey was the first one to notice.
"Ahhh, the little brat sh*t herself!" He said, placing a leaf/hand over where his nose would be.
Undyne turned to Flowey. "One more outburst like that, and I'll break out the soap!" She said, scowling. Then Undyne noticed. "I think Pedals is right," She said, covering her nose. Soon they all were holding their noses, except for Frisk, who was crying.
Flowey then asked the question that everyone had in mind. "So who's gonna change her?" He asked, still holding his nose.
"Oh, don't look at me, I don't know how," Papyrus said, handing Frisk to Alphys.
"I'm sorry, I'm not good with diapers," Alphys said, setting Frisk down. They all turned to Undyne.
"No! No way! I will not!" Undyne said, folding her arms. Even though she used to babysit Asriel, she did not want to have to change Frisk.
"Didn't you babysit Asriel when he was little?" Papyrus asked.
"Yeah, but I never liked changing his diapers!" Undyne replied, annoyed.
"You're the only one who knows how to change diapers," Alphys said.
"F-Fine! I'll do it!" Undyne said, picking Frisk up and holding the child away from her. She walked up the bathroom, and tried to remember how to change a diaper. When she finished, Frisk was still crying for some reason. She sighed and picked the child up. "Please stop crying," she pleaded. Frisk wouldn't stop, she just kept crying. Then Undyne had an idea. She remembered what she would do with Asriel. She tossed Frisk up in the air, and she caught her. She tossed her higher and higher. Frisk seemed to enjoy this, because she started laughing within seconds. After about ten times, Undyne caught her. "I think that's enough birdy for today," she said, remembering the name Asriel had given it. "You're pretty cute, you know that," she said, ruffling Frisk's hair.
"Undye!" Frisk managed to say.
When they got downstairs, Undyne had another idea. She took Frisk to her room, and she got her suit of armor out. She smiled and placed the headpiece next to Frisk. Frisk grabbed the headpiece and tried to lift it, but it was heavy even when she was at the proper age. Undyne went to pick the headpiece up.
"No!" Frisk said, trying to push Undyne's hands away. She grabbed the headpiece again and tried to lift it. Undyne thought this was adorable, Frisk was determined even as a baby. After a minute of trying to lift the headpiece, Frisk stopped trying and tears welled up in her eyes.
"Hey hey, don't get upset, we can lift it together," Undyne said, grabbing Frisk's hands. With Frisk's hands in hers, Undyne lifted the headpiece off of the floor and placed it on Frisk's head. Frisk immediately fell back due to the weight of the headpiece. She tried to get back up, but couldn't. Undyne helped her stand up, but caught her when she fell forward. She held onto Frisk's arms as she helped the child walk with the headpiece on. After a bit, Frisk's knees gave, and she fell on her behind, causing the mask part of the headpiece to slam shut. Undyne chuckled at this, and grabbed the other parts of the suit. She set the chest plate down, and placed Frisk in it. She placed Frisk's arms in the arms and set the legs side by side on the ground. She lifted Frisk, armor and all up, and placed Frisks legs in the armor legs. Frisk wobbled in the armor, and fell forward with a clash. Undyne helped her up and helped her walk in the armor. After a bit, she helped Frisk out of the armor and put it away. She picked Frisk up, and took her to a key board that was in her room. She sat down with Frisk in her lap, and she used the child's hands to play a song. Frisk seemed to get the hang of it, because when Undyne let go of her hands, she hit her hands against the keys, as Undyne watched smiling.
The key board concert continued until Frisk let out a yawn. "Tired?" Undyne asked, picking her up. Frisk nodded and rested her head against Undyne's shoulder. Undyne took Frisk down to the couch and sat with her. Soon, Frisk was fast asleep, and Undyne drifted off not long after.
