Bob has a problem. Living as he does among the chickens, all he can do is cluck. But Henrietta the cat sets him straight: "Bob.-You need to stop clucking and learn how to crow-.That's what roosters do." This advice sends him on a search among the animals of field and forest for one who will teach him to crow. Before he gets it right, Bob has learned to "meow-meow," "woof-wag," "ribbet-ribbet-hop-hop," "moooooo," and even "yum-yum-bugs" (a substitute for cud-chewing); but he finally meets Fred, a rooster who obliges with the proper lesson. Back in the henhouse, Bob is too excited to sleep, so he is wide awake when a fox comes in. His "cock-a-doodle-do" doesn't scare the villain, but the rest of his repertoire terrifies the intruder, particularly his "yum-yum-fox." From then on Bob wakes Henrietta and the girls each morning, either with "cock-a-doodle-do" or, if he feels like it, with "Meow-Woof Ribbet-Moooo Yum-Yum-Bugs!"
