Fans of Superfudge and Fudge-a-Mania will welcome the return of seventh-grader Peter Hatcher and his five-year-old brother, Fudge, who in this comical caper meet distant cousins from Hawaii. The two families unexpectedly encounter one another in Washington, D.C., where the New York City Hatchers have gone so that Fudge, who has developed an obsession with money, can visit the Bureau of Engraving and Printing. The Howie Hatcher clan proves an eccentric lot. Twins Fauna and Flora, un-ironically nicknamed the Natural Beauties, would be in Peter's grade if they weren't home-schooled; apt to break into corny songs at any moment, they perform together as the Heavenly Hatchers. Their younger brother, who shares Fudge's real name (Farley Drexel), acts like a dog, growling and licking people. And their father won't stop calling Peter's dad "Tubby." Narrator Peter grits his teeth when the Honolulu Hatchers invite themselves to Manhattan to stay in his family's cramped apartment, where nestled in their sleeping bags on the living room floor they "slept flat on their backs, like a row of hot dogs in their rolls. All that was missing was the mustard and the relish." The boy is further appalled when the twins show up at his school and convene an assembly so that they can sing. Peter's wry reactions to the sometimes outsize goings-on, Fudge's inimitable antics and the characters' rousing repartee contribute to the sprightly clip of this cheerful read.
