The Shore is the Border

“Snufkin!” cried Moomin, treading the surface of the water.Snufkin couldn’t help but stare. Moomin’s face looked different – there was a patch of golden scales between his eyes, and his white fur had turned as sleek as a seal’s. And his voice – it was so hoarse, as though it pained him to speak. “You’re back! Oh, I’ve got so much tell you!”“Clearly!” said Snufkin. “Moomin, what happened to your paws?”Moomin’s lifted his paws further out of the water. There was golden webbing between his fingers. Moomin stretched them out, the sunlight making them glitter.“You should see my tail,” said Moomin with a weak laugh, lifting his tail out of the water. Instead of his brush of soft fur, his tail now ended in a little fin, the same golden colour.--While Snufkin is on a trip, Moomin gets a potion from the Witch to spend half a day under the sea. But the incantation to turn him back didn't work. So Snufkin returns to find a Moominvalley in turmoil, as everyone desperately tries to find a way to turn things back to the way they were.
