Wiley and his friend Jubal experiment with a chemistry set and develop a dangerous new explosive named PPK. The next day, just as Grampa's barbecue festivities are getting underway, the recently deceased begin rising from their graves! And they sure are hungry for barbecue! When the zombies devour all the delicious grub, their appetite shifts toward the living. Only Vera the lunch lady's spicy beet borscht can save the party-goers now.
When Wiley and Grampa courageously set out upon Lake Putrid to catch the infamous Moby Fizz, they'll brave more disgusting dangers - particularly Gramma's homemade pimento and cheese - than Grampa's trusty fishing net can handle.
Sitting around poppin' pork cracklins and watching the tube, Grampa and Wiley witness to the awesomest TV commercial they've ever seen: Colonel Dracula's Monster Truck Spectacular is in town! Then the local weatherman breaks in with a dire warning: an F5 tornado could blow through at any minute! So what does a responsible guardian like Grampa do? When Gramma isn't looking, he and Wiley sneak out of the house bound for the monster-truck extravaganza, of course!
