Neville's Grandma is visiting the same weekend as his troll friends,
which can only mean one thing: trouble!
Hullo, My Brandyburp! 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?
