Fate comes in all shapes and sizes and...ages?

A new puzzle

 Disclaimer: All characters belong to their rightful owners and Toby Fox is to be credited as  the maker of Undertale. There is some mild cussing and some mild violence throughout. NO child abuse. 

 Once Sans successfully managed to ease the child into sleep he steadily continued his march through the snow. His plans for the day altered drastically with an odd newfound purpose in mind. There is a life in his arms...innocent, depending on him.  

He was debating whether he should dump the kid on someone else and let things go back the way they were OR let his bastard of a brother find out about the child and take it to Asgore. 

But he knew that any credit offered would be soaked up by his tall self absorbed evil sibling, Sans name would be either muttered in mention of the capturing of the human or excluded entirely. 

Either way Sans knew the excitement would wear off if he did turn the human over to Papyrus and that things would slowly die down back the way they were. 

So with the new resolve to keep the child a secret, he did his best to steer clear of his brothers post. Sans stops at a gate, a poorly made gate due to his brothers foolishness at making the bars too wide making it easy for anyone to slip past. 

With Frisk in his arms he goes in sideways and slips through, he looks side to side cautiously for any signs of his brother. Fortunately there seemed to be none making Sans relax and keep walking. 

All seemed to be going well, no greater dogs, no Undyne, no Papyrus and the kid was aslee-

" Wuh wuu waaaaah"

 'Damn it'

Sans cursed in his head, looking down at the bundle he had in his jacket to keep warm while she wiggled and wailed in a uncomfortable and irritated manner. 

"Alright alright already," Sans groans with annoyance and pats her back trying to assess the issue. 

" SAAAAAANS!"

'Damn. It.'

Sans felt his day just getting worse, he quickly shoves a old yet washed mustard bottle top in the childs mouth and stuffs her gently down in his jacket where his visible  belly bump is usually, making sure she can still breath and closes his jacket up looking at Papyrus. 

" Oh, hey ya... boss." Sans manages through clenched grinning teeth.

" Sans, you were not at your post today! AGAIN! For the last damn time Sans, get your shit together and do something right for once you lazy arse!" Papyrus roars with fury fueled by exasperation and annoyance.

" Awe well gee Boss heres the thing, that job is really bone dry and I'm not sure I have the heart to give it my all. Its boringness is getting under my skin ya know?"

Papyrus narrows his eye sockets at Sans, this was NOT the time for more of his utterly ridiculous childish puns! 

" Sans! I swear! If you say one more stupid pun I shall pound your smiling ass down in the ground so far that–

" WAAAAAAAAAAA"

'Shit, couldn't the kid picked a better time to scream their head off?' Sans wondered with annoyance.
