BF: They would just sing and dance

GF: Well this would happen Sunky: so you are a demon... but like, a good demon, not the 'I am going to take your soul demon' GF: ... yeah, pretty much... Sunky: Ok

yeah that's it

Pico: Well Sunky would try to get rid of the guns, and Pico would see him, think he's some alien like Casandra, and try to kill him

Skid and Pump: They would play along with the whole "Spooky mounth" thing, dispite knowing that it's not Spooky mounth at all

Daddy Dearest and Mommy Mearest: Sunky would call them meanies and not talk to them

Now for mods

Boy N Girl: By the logic of BnG they can't meet because Sunky is not a kid, bad person, and not really a monster. But if they did meet they would have a dance party and, while Girl doesn't eat much, Boy does so they might eat cereal as well. Yes, I read all the lore on these two to know that.

Witty: Sunky would just let him do his thing

Tricky: They would get hotdogs together

Sky: Sunky would know that something's odd about her and walk away

Ski: They are canonically already friends, but they would eat cereal together... again

Tails doll: Sunky would try to befriend him and fail

Sarv and Ruv: Sunky would just join, not because of religion, but because he would try to befriend them, or at least be on their good side

Pibby mod characters: He would live

Shaggy: They would get sandwitches

Matt: They would have a boxing match, and Matt would win

Lord X: Sunky would take over his game

MX: Sunky would run from him

Suicide Mouse: Sunky would try to cheer him up, he would start to cry because he lost every thing, and Sunky would start adding color to the cartoon, what this would do, I don't know

Edd: They would drink coke

Garcelo: Well Garcelo would already be dead, so Sunky would have a funeral for him, and he would show up, as a ghost, to his own funeral

Bob: He would try keeping Bob happy

Ron: They would have a meme contest
