A seemingly normal day at the clinic turns strange when a magical creature begins making wild prophecies, when he usually just predicts the weather and helps find lost household items! Meanwhile, a mysterious magic in the water makes river creatures, both magical and normal, behave in odd ways. Beavers build elaborate wood houses teetering on the edge of collapse, kelpies cast aside their magical disguises when trying lure people to the water, and ice swans make ear-piercing mating calls and freeze chunks of water solid-all similar to the creature at the clinic.
