When the Elephant Walks

``When the Elephant walks . . . he scares the Bear,'' begins this whimsical chain-reaction story. Bear, who is interrupted as he tries to raid a beehive for honey, runs away from the Elephant. Bear then scares the Crocodile, who is relaxing and reading a newspaper. The Crocodile dives into the water and swims for his life. In turn he frightens the Wild Hog who, with goggles on his head and a tube around his middle, is poised to take a dip. And so on, until a frightened mouse scurries into . . . guess who? The elephant, of course, trembling in terror. Kasza ( The Wolf's Chicken Stew and The Pigs' Picnic ) fills her pictures with amusing details that children will appreciate along with the simple story. Especially entertaining are the expressions on the animals' faces. Ages 3-6. (Apr.)
