You were exploring when you got into a lab. "Ooooh!" You walked around, seeing tons of containers filled with different colored liquids. Thats when you saw a giant Gaster blaster. "Puppy!" "(What ever sound a confused Gaster blaster makes)."

-Later-

"Error look!" Error flinched at you being ontop of Gaster's blaster. "Kid... get off him or Gaster is going to kill me..." "BUT ITS SO CUUUUTE!" The Gaster blaster purred and flew around, now Error was chasing you on your new pet.

You stood on it and flew on it like a skateboard, "Totally fresh dude!" Fresh yelled, you smiled and leaned forward. "I think we lost- AAAAAAAH!" You found yourself in string with Error on a string hammock. "Put me DOWN." "Nah." You puffed your cheeks and whistled, having your Gaster blaster come over and bite the strings.

Error chuckled and hopped down, seeing you petting the Gaster blaster on the couch. "Hey (y/n)~!" "ERROR NO!" You squealed and giggled as Error tickled your side and rib cage. "GOTTA! TICKLE TICKLE TICKLE!" "NOHOHOHOHOHO!" Your Gaster blaster was nuzzling your skull in this tickle attack, Error kept tickling you till you looked like you needed air.

"I got you good. Admit it." Error said, pulling you into a hug with your Gaster blaster on your lap. You smiled and nuzzled Error's chin. "Ok. You did get me." For the rest of the day, you, Error, and (dog's name) the Gaster blaster napped.
