The very persistent gappers of Frip
(Book)

"In the seaside village of Frip live three families: the Romos, the Ronsens, and a little girl named Capable and her father. The economy of Frip is based solely on goat's milk, and this is a problem because the village is plagued by gappers: bright orange, many-eyed creatures the size of softballs that love to attach themselves to goats. When a gapper gets near a goat, it lets out a high-pitched shriek of joy that puts the goats off giving milk, which means that every few hours the children of Frip have to go outside, brush the gappers off their goats, and toss them into the sea. The gappers have always been everyone's problem, until one day they get a little smarter, and instead of spreading out, they gang up: on Capable's goats. Free at last of the tyranny of the gappers, will her neighbors rally to help her? Or will they turn their backs, forcing Capable to bear the misfortune alone?"--Excerpt from Amazon.com.
