A lonely skeleton

OKAY SO, all of the characters don't belong to me exept ghost sans or whatever i call this au that i made up at school lol but anyways its about my sans meeting other au's a.k.a appearing in their au's becouse why not? :v
okay so a quite flashback of this au that i made up:
ink was in a happy mood since error FINALLY stopped destroying his precious au's (he even meant underlust au lol) tho he knew he had to take this chance and decited he wanted to make a very happy au, he slowly set the story like "a smoll child frisk falls in happytale (since he ran out of
idea's) the other monster's and sans and papyrus will be in good terms with others and the child," ink was proud that he finally made a great au tho soon he forgot about it's existence and slowly but painfully the au became chaos, the things happend floor in the au was cut in half in a not so straight like and monster's died the child frisk killed them and sans became quite mad and angry so he had a battle with frisk (lol) soon enough frisk got close to him and jumped on him attempting to stab him but failed so they tried to stab him in his eye (?) tho they made a crack on his skull (sence becouse she has an axe instead of a knife... bro what did papyrus do?! ofc he gave them an axe becouse they asked him to and papyrus was VERY nice) tho when she jumped at him sans fell on the ground so he cracked his head (?) a little bit...tho he got up and then bla bla fought them bla bla bla they winned and killed him so now Ghost sans was made, the kid frisk somehow escaped the underground (logic?) and the place was left in ruins then happy-tale changed into ghost-tale sience the whole underground was now full of ghost's, sans decited to name himself "ghost" as simple as that is, and soon became a loner traveling to diffrent universes of himself to find a place to enjoy, "he also had a puppy with him sience the puppy was still alive he could not touch it but the puppy could see him, the doggo is happy
