y/n p.o.v.

I look around it look so nice then what caught my eye was papyrus"awww,gaster your son is adorable,""thank you, wait  where's sans,"i saw sans coming out the kitchen with red bottle"i'm right here,dad,"gaster brought both of them over to me"i would like you to meet y/n,"sans held out his hand"sans,sans the skeleton,""nice to meet you,i hope you have a SKELETON of puns for me,"papyrus was trying to hold back his anger"sans,don't you dare,"sans then said"okay now i have a BONE to pick with you,""SANS!,"papyrus yelled"ah,come on bro,i see you smiling,""i know and i hate it,"me and ink started to laugh,gaster came to my side"you ready?,""i was BONE ready,"gaster chuckled and shook his head,then he was gone,ink walked over to me,"so uh what are we supposed to do again?,"wait did he forget that fast,"we are supposed to just take care of them while gaster is away,""oh okay,"sans was starting to get on papyruses nerves,his left eye went blue and he held a bone in his hand,he started to chase him,papyrus ran into a dark room,sans stopped where he was and started to take steps back"y/n!,"then he started to run away,papyrus came out with a chainsaw "nyeehhhh,"

I ran over to papyrus and nicely grabbed the chainsaw"i know you want to get revenge on your brother but i have a better solution,ink can you keep sans busy,""sure,"i took papyrus into the kitchen"are we making spaghetti?,""no,this is going to be a prank to get your brother back,can you get the hot sauce out and one of his ketchup bottles outs,"papyrus went and got the bottles and placed them on the table,"okay so i want you to take out the ketchup in this bottle and put the hot sauce in the ketchup bottle,"while he was doing that i grabbed all the hottest spices i could find and helped him put in the bottle,then i grabbed the peppers and i noticed that these were peppers are the hottest peppers in the world,a carolina reaper,now this is going to be funny,i placed it in the bottle"now take this to your brother and say sorry,"i winked at him,then he put on his serious face,and walked over to sans,i walked over to ink"watch this and record this,"ink took out his phone,papyrus hand sans the bottle"i'm sorry for the chainsaw scene,""aw,brother you didn't have to,"sans took a big gulp of it,then i looked at papyruses face, it looked like a demon has awakened,sans face went black"uh papyrus what is in the ketchu-aaaaaaahhhhhhhhh!,"sans powers went crazy,i quickly grabbed the milk out the kitchen,and hand it to sans,he drank it so fast it didn't help"papyrus i'm going to kill you!,"he yelled as he fell to the ground looking up to him,ink ran over to sans and put some type of food in his mouth,so he would stop yelling,"ink what is that stuff,""chocolate,it's helps a lot,"sans started to calm down"papyrus now that you have done that i'm going to kill you.....with puns,"i turned and looked at the time 7:40pm"uh, hey,what time do you'll go to bed,"papyrus and sans looked at me"well,8:00,but do we have to,go to bed,"ink but in "if you do we'll,hm we'll let you,uh to your friend grillby's,and mettaton,"the two boys ran upstair and got in bed.Me and ink tuck them in but sans and papyrus grabbed our hands"can you sing us a song?,"ink looked at me like i was going to do it so i did.{to lazy to write thr song out here it is}

Ink looked at me"good job their asleep,and i never knew you can sing,""i have my ways,"then gaster was behind me and started to talk"thank you y/n i have all the important information i need,"when gaster scared me i jumped into ink arms"oh sorry y/n ,"i slowly got out of ink's arms"it's okay,oh and one thing,i promised them that i would take them to grillby's and mettatons,""oh okay thank you for telling me, i'll take them tomorrow,and here,"gaster handed me this bag of food wrapped up"thank you,"it smelled to good.After that gaster watched us go back to the void.
