From the description: You’re supposed to be setting up your place for a sweet birthday party. But your neighbour is coming, and they’ve been watching too many YouTube conspiracy videos! And they might be an extraterrestrial! Can you throw a birthday bash without them making it weird? Uh, Dang! My E.T. Neighbour Is A Conspiracy Theory Guy is a sequel to Oh, Dang! Bigfoot Stole My Car With My Friend's Birthday Present Inside and Ah Dang! Mothman Won't Move Out (He Said It Was Just For The Weekend) about a birthday party that's out of this world.
