Weirdmaggedon of Spooky Doom by subtle-witch reviews
In which Dib finds a forum where he can talk to other supernatural enthusiasts, Gaz starts a sweater business with an anonymous online friend, Mabel thinks she's acquired her new online love, Waddles eats some waffles much to a robot dog's disapproval, and Dipper travels to a very strange town. Not as odd as Gravity Falls, of course. (Title may change. Cover image not mine.)

Be Careful Making Wishes in the Dark by Jaywings reviews
"So we have a deal, then?" There was something in Bill's tone that Dib wasn't sure he liked, but he pushed the feeling to the side. If this was a chance to expose Zim, he had to take it. Nothing else he'd tried had ever worked. "Yeah."
