Error glitches heavily, huffing in anger.
"But- but... Errrooorrr!" Nightmare complains.
"Not now!" Error glitches, slapping a tentacle away.
"No touchie!!" Error screeches, clinging to a giant bag of chocolate Dream had bought for him.
Nightmares single eye twitched.
"Youll get a stomachache! Now give. Me. The. Damn. Chocolate."
Nightmare puts a syllabus to each word, snarling. Error screeches again as Nightmare tackles him, trying to wrench the bag out of Errors grip.
"LET GO!"
"OVER MY DEAD BODY!"
"IS THAT A CHALLENGE?!"
"FUCK YOU!"
"ILL DO THAT LATER!"
Dream snickers, watching from the kitchen as the two wrestle.
Error finally struggles out of Nightmares arms and teleports away. Nightmare gasps and stands up, then notices Dream. Dream squeaks and runs.
"IM GOING TO MURDER YOU!" Nightmare howls.
Poor Dream ended up hiding in a cupboard for the rest of the night and the next day, until Nightmare found him the next evening, extremely worried and kept apologizing to him.
However, Nightmare would never tell how worried he was.
