Polacco again exercises the surprising streak of goofiness revealed in The Graves Family (2003). Doug and Shalleaux Graves take off, with attendant children, oversized spiders and other household companions for Lake Bleakmire—a site so isolated that, along with Vernicious Knids, gnashing knarps, bilge leeches and other atypical fauna, the last Flatulent Sulphuric Fermious Flying Griffin (more commonly known as fire breathing dragon) lurks. Several misadventures later the Graves break away, despite the lonely monster’s efforts to trap them, only to discover back home that it has followed along, eager for more of Mrs. Graves’s delectable Jum Jill pastries. Wielding her brushes in a quicker, more cartoony fashion than usual, Polacco places her freewheeling, carrot-topped clan amid all sorts of oogy creatures, capped by a scaly, bat-winged behemoth whose explosive eructations ultimately provide the town of Union City with its most spectacular Fourth of July fireworks show ever. Delightfully gross and utterly unserious. (Picture book. 7-9)
