(Heyo! I got the idea when sis was playing basketball. Hope you like it!

OVOVOVOVOVOVO

Sans looked at the basketball in his hands, staring blankly at it with hollow sockets. "paps said i should get ready when a human comes." He said to himself and mindlessly dribbling it, "which means imma have to battle it. i better practice on that, i'll just leave a Monster Kidz Word Search for my puzzle." He thought and left himself grin as he imagined his brother nagging him about being lazy.

"welp. i am a lazy-bones." He said and kept dribbling his basketball while walking around the woods. "ya know, if i'm going to battle a human i better get a dummy." He said out loud then looked at the bouncing orange ball.

A grin crawled up his face.

OVOVOVOVOVOVO

Sans let out an airy chuckle at the new look of his basket ball. It had three lines on it, two were on top as closed eyes while the third one was slightly below as the mouth. A stoic face. "heh. i was never good at drawing." he admitted out loud and decided to play with it.

He closed his eyes and readied himself. Slowly (or lazily), he dribbled the ball then caught speed moments later, a make-shift hoop was awaiting him by a specific tree and Sans' right eye started to glow, "GEEETTTTTTT-"

He jumped and contiued, "DUNKED ON!" The phrase was rather natural to Sans and he felt that he would have to use it for the future. "man, that was fun. " He chuckled and let the ball twirl on his pointer finger and went back to his post for a nice little nap.

Sans stared at the human. They had dropped their knife, using mercy for the first time since they got here. Sans stared intently and he let out a chuckle. "you're sparing me? finally. buddy. pal." He stepped up, making it look like he was taking the bait.

"i know it must be hard for you to make that choice. to go back to everything you've worked up to." He closed his eyes then opened them again, sweat still pouring. "i want you to know... i won't let it go to waste."

He let his left eye rest and held out his hands in a hug. Like the human did when they dropped the knife. "c'mere pal."

He grinned and let his hands shot up higher, bones emerging from the floor, killing the human instantly. Their HP was dropped to 0. "GEEETTTTTT DUNKED ON!" The human's blood spilled on the floor and he stared at the humans' stoic face.

"i knew i was going to use that phrase one day." He bluntly said out loud. The scene zooms out as he recalls, "pretty sure you had the same face like that ball."

"huh. you were pretty fun too when you were a ball. guess killing you instead of dumping you was much funner." He chuckled.

(Thanks sis for the idea :3)
