If you guys don't know this is Mannie Dex from lost in Random.
He reminds me of sans for 4 reasons:
1. He is literally everywhere (Even at the very end of the game!)
2. All of his encounters take place at a vendor (Like sans sometimes)
3. He is a pretty chill dude.
4. He is some sort of monster.

(If I see a theory short of any franchise on YT shorts, this sentence is usually said in the background)
