"It's Halloween today" Dipper mused, lying on the couch.
"No shit Sherlock" Mirage's eye twitched.
"SPOOPY SCARY SKELLINGTONS, SEND SHIVERS DOWN YOUR SPINE!" Bill sung loudly in the background.
"I wonder what we should do" Dipper continued, as if his husband and seventeen year old daughter weren't there.
"Nothing?" Mirage asked hopefully.
"Trick or treating!" Illusion –Bill and Dipper's six year old son- shouted.
"The last time we did that you made the other kids think you'd chopped off your own head, no" Dipper shook his head.
"I have an idea!" Bill yelled.
Five minutes later, the house had turned into chaos.
"Dads" Mirage glared at her parents.
"OOOoooOOOoOoOoOOOOO" Bill said from underneath the sheet with holes in it.
"Dads" Mirage said again.
"I AM A VENGEFUL SPIRIT OUT TO GET YOU!" Dipper wailed, chasing after a screaming and laughing Illusion.
"God freaking damn it" Mirage growled, stomping up the stairs to her room as she cast an illusion of her respective dads' worst fears.
"NOW THAT'S A GOOD HALLOWEEN TRICK! GOOD JOB MIRAGE!" Dipper praised.
Mirage groaned and rolled her eyes at her fathers' excitable antics.
