((Guess I'll participate.))
There's a pillar of blue light that appeared out of nowhere in the distance, and then it disappeared. Everyone can see 2 figures. One of them threw something in the direction of the picnic. The other figure raised its hand and something blocked the object before it even reached 3 metres. You can read their mouth movement to find out what they're talking about.
"Why'd you block my javelin?"
"..."
"Fair enough. Let's just go there and enjoy the food"
"..?"
"I think we should just walk over there. Hmm, try not to use our powers too much? Sure I guess, but if they make the wrong move, I can still kill them, right?"
"..."
"Fine."
Looks like the guy who blocked the projectile doesn't move his mouth often or his mouth is in a fixed spot.
After some time, they reach the picnic spot.
"Heya. I'm Sans, and this is B-"
"I'm Betty!"
Sans reaches out to take a bottle of ketchup and a hot dog but remembers that this is a picnic and everybody shares the same food. Betty returns with some marshmellows she looted from a snowman's melting corpse took from a snowman.
"Want some?"
"Sure. Thanks kiddo."
