A simple book app with charming, hand-sewn illustrations and twelve different surprises to encourage repeat play. This is the story of Billy whose coin visits the zoo (although it’s not clear whether Billy himself ever actually gets to the zoo) after being dropped down a grate. The coin bounces along, being tossed from one animal to the next until it finally makes its way back to Billy who uses the coin to buy a ball from a coin-operated dispenser. The ball opens to reveal a wool felted animal. There are twelve different animals to discover in the balls (you get a new ball each time you read the story) and each is accompanied by an interesting fact about the animal. The rhyming story is presented using just two to three short lines of text per page. The illustrations are crafted from a variety of fiber materials with charming imperfections. Users can choose a male or female narrator or can turn off the narration completely for a read-it-yourself experience.
