Some silly, limp make-believe--featuring a scruffy (elderly, bald) knight, Sir William, and the ""half-animal,"" ""half-machine"" Machinosaurus (more or less a giraffe with wheels), who's giving Sir William's neighbors a hard time. After the Machinosaurus eats Burly bear's porch, Ollie owl's cellar, the top of nice, pie-making Mrs. Water's trees, Sir William confronts the beast: why does it eat only parts of things (when it could gobble down the whole)? Seems that the monster doesn't really like what it's eating--but ""I have to eat something."" So Sir William stanches the creature's hunger with Mrs. Water's succulent pies. From start to finish, about as synthetic and pointless as they come (and a real washout for kids of an age to read).
