Buffy has a toothache, but no dental insurance... as if her financial problems weren't overwhelming enough already. And Anya and Xander are being held hostage in their own home by a plague of ants. Everyone is determined not to sweat the small stuff -- until Spike discovers economy-sized evil wreaking havoc in Weatherly Park. Mini-monsters are perfectly capable of mega-trouble, and in order to stop them, the Slayer's going to have to think... small!
