Your kin lies down for the night, and when next they open their eyes, they are a wolf. Their companion wolf is beside them. What happens from there is up to you -- do they hunt together? Do they race, go for a swim? Do they fight? Be creative, or go for a classic.
It was chilly, and Night's Whim was in the swamp, where the evenings were getting cold enough to frost - not his favorite, if he were honest. Curling up for the night, he was grateful for Stout Heart, who obligingly curled up beside him. Laying his head across the wolf's back, Whim huffed contentedly, closing his eyes and letting sleep take him.He came awake with a jolt, and felt...different. Heart racing, he sat up, and looked over, directly into Stout Heart's eyes. Everything felt slightly off. Why was he so close to the ground?! Getting to his feet, he looked down and saw..paws? Stout Heart yipped, tail wagging, and Whim decided that whatever the reason, this was fun! Nudging his companion lightly with his own muzzle, before darting off into the darkness, with Stout Heart hot on his heels. He splashed through mud puddles, leaping over small logs (and occasionally, shimmying beneath ones that were taller than he was). Occasionally, Stout Heart passed him, and it was his turn to give chase, stopping from time to time to roll around playfully in the dirt. They didn't stop until the first rays of dawn began to streak across the sky, and they finally collapsed in a wolfy pile of panting fur.
With a gasp, Whim woke up, back in his own body. Stout Heart snoring softly beside him. What an odd dream...But why am I covered in mud???
