Revenge of the Lawn Gnomes

Two pink flamingos. A whole family of plaster skunks. Joe Burton's dad loves those tacky lawn ornaments. But then he brings home two ugly lawn gnomes. And that's when the trouble starts. Late at night. When everyone's asleep. Someone's creeping in the garden. Whispering nasty things. Smashing melons. Squashing tomatoes. No way two dumb old lawn ornaments could be causing all the trouble. Is there?
