Someone or something in the village of Knobbly Bottom is eating up EVERYTHING!
When a chocolate cake goes missing, nine-year-old Maggie McKay gets the blame. But when entire vegetable plots are devoured overnight, huge bite marks are found in garden furniture and even her friend Fred's grandad's disgusting courgettes are gobbled up, she kicks off an investigation!
However, when the ravenous local pigs start turning green and doubling in size, Maggie and Fred wonder whether they might have bitten off more than they can chew... How can they fend off the rise of the ZOMBIE PIGS?
