When Polina told the whale her own story, he said, "I'm headed north anyway. You could ride on my back, and we can look for your mother. Are you ready for another adventure?"
The next morning, Farswimmer and Polina charted their course and took off. Polina rode Farswimmer's back and sometimes floated behind him, holding his tail. She also stood on his back and pretended she was surfing. It was a blast.
