Sans walk down path to child.

"Kid want bad time?!?"

Kid not want bad time because bad time bad.
Kid turn into different kid, to save self, but it did not work, cause kid was still ugly.

Sans punch kid, sending kid through ceiling of cave, freeing from having to go through the undertale game..
Destroying life and fandoms for the skelebros..

Cave fall in on the underground.
Everyone go bye bye into underhell and underheaven.

Kid go back home to dumbster behind mcdonalds.

Horray.
