One morning, Flipper the Seal discovers a big, round 'thing', sitting on the ground. He wonders what it could be. He shows it to Snowy the Fox, who sniffs and licks the object. He doesn't know what it is, but he doesn't think it's anything to eat. Then Hoppity the Hare comes along and taps the strange shape. She cannot work out what it is, but it sounds as if there's something inside. Then Wally the Whale swims up to take a look, but he doesn't have a clue either.
