Neville's Grandma Joan is the grumpiest, most horrible old woman there's ever been. He'd rather eat left-sock stew than see her, and now she's coming to stay for a WHOLE weekend. Oh dungle droppings!
Even worse, a whole family of stinky, swampy trolls will be visiting Neville at the SAME TIME!
Can Neville hide his friends from nosy Grandma Joan or will she get the FRIGHT of her life?
