Chapter One: The Shortcut

The two skeletons were walking back to Snowdin when Sans asked. "Hey bro, wanna go to Grillby's?" "But Sans you always want to go to Grillby's!" "Come on bro it's a good place to Ketchup on past events." "Nyeh! Sans what have I told you about you puns?" "Whale you told me to stop and I did stop them for that day." "Nyeh! Sans stop making so many puns!" "Fine I'll stop the puns for the rest of the week if you go to Grillby's with me, okay?" "Fine Sans let us go to Grillby's." "Hey I know a shortcut you wanna come with?" "Fine even though I hate going on those shortcuts. I, The Great Papyrus, does not feel like walking in the cold along with walking without my brother." "Okay follow me bro." *Voomp*. A portal appears in front of the two casting a calm blue light upon them. "Here we go."

Meanwhile

"Hmm I wonder."says Error Sans with the I distorted. He pulls on some of his strings.

As Sans and Papyrus were walking through the portal the usual blue glow turned into a dark shade of red. "Sans w-what is happening?" "I don't know bro, but whatever it is I don't like it." Error signs started popping everywhere. A shadow appeared from the ground. "Sans, Papyrus quickly over here before it's too late."said the shadow as it opened another portal. "That voice…" "Sans now is not the time to be lazy come on!"shouted Papyrus as he lifted up Sans and ran towards the portal. "Wait, bro!"shouted Sans but it was too late, Papyrus already jumping through the portal.

Thump!

"Ugh. Pap are you okay?" "Nyeh. Yes i am okay Sans." "Hmm it seems that you two are rattled to the core." "Oh haha Gaster." "Nyeh! Why, why me? Why do I have to put up with this?" "Sans why do you insist on calling me by my first name? I am your father." "Wait what? Sans that is our father?" "Yeah but where are we?" Looking up Sans and Papyrus didn't recognize their surroundings. "Well to be honest I don't know." "Wait that means we aren't at Grillby's." Sans smiles with a chuckle. "Oh no.." "Well I think there was a slight error in my calculations." "Sans now is not the time for puns." "Hey wait am I the only one who sees… sunlight?" "What? Sunlight does that mean we are on the surface?" "It seems that we are but not our surface. I don't sense the other timelines." Gaster says as he looks up at the source of the light.

Well cliffhanger time. Yeah I know I hate cliffhangers but I'm getting tired of typing. Oh yeah in future chapters there will be references to my other crossover One Punch Hunter?
