Someone has just stolen Ruff's garden gnome and he's determined to get it back! In fact, he's so obsessed that he hasn't bathed in several days and is covered in flies-prompting Charlene to send him some fly swatters. Ruff sends Emmie and Marco to the Amherst College Museum of Natural History to analyze the footprints left behind by the perpetrator who stole the garden gnome; while Rubye and Shreya try to barter the flyswatters for something better that Ruff can give to Charlene.
