When Duck accidentally crashes into Spider's web and breaks it apart into letters, he has to go about finding the letters to fix it. But he doesn't know what letters are in the word 'web'! With Elephant's help, he learns that sometimes if you can sound out a word, you can figure out what letters you need to build it. / Duck makes a new friend on a windy, rainy day: Caterpillar. It soon becomes apparent that Caterpillar needs a home to protect her from the elements. Together she and Duck learn to sound out some words which might make suitable homes, such as BAG, CAN and BOX. But which one will be just right?
