In Westaway’s first picture book, originally published in Australia, a whale has invaded the bathtub of a boy named Bruno; worse, it isn’t even an especially nice whale. “You could have knocked!” says the cetacean before shooing Bruno out of the bathroom. Bruno tries to explain the situation to his family, but no one believes him. “A “shower” courtesy of the whale’s blowhole keeps Bruno from getting in trouble for not bathing, though, as his mother notes, “You smell a bit fishy!” While there isn’t much of a story line, illustrator Jellett makes the most of the improbable situation, filling the bathroom with bubbles and white spray to emphasize the mess the whale is making and using crayonlike red scribbles on Bruno’s cheeks to highlight his growing irritation. Good, clean fun!
