"They call me Farswimmer," said the whale, "because I travel all over the world, having adventures and learning new things. What brings you here, Polar Bear?"
Farswimmer was very old, and he had seen many changes in his years of exploring the oceans. He certainly knew more about the world than most polar bears. To help him remember, he wrote songs about the places he'd visited and the things he'd seen, and sang them to himself as he swam.
