Weirdo Halloween (Goosebumps Horrorland #16) - R.L. Stine - Bog

Chris and his twin, Meg, have a problem. It started the night before Halloween when the twins found a gang of bullies hassling someone in costume. The twins rescued the kid-only to find that it was a bald, pink alien who promptly swore allegiance to them. "Weirdo" is smelly and gross with a lot of disgusting habits, and the twins can't shake him. Little do they realize that their troubles are only beginning. Weirdo's invited hundreds of aliens to town on the 31st for a full-scale invasion-and to come live in the twins' house! Will the HorrorLand souvenir save-or harm-them? In Part 2 of this Goosebumps HorrorLand Halloween Special Edition, Chris and Meg find themselves back in HorrorLand, where Jonathan Chiller sends them and the kids from GBHL 13-15 on a mysterious and terrifying Halloween adventure inside the park. HOW WEIRD CAN HALLOWEEN GET? Continue the summer with the fourth book in the newest seven-book HorrorLand arc.
