Mother called them all, summoned them back to the Den, and mostly they went. All Brothers and Sisters turned tail and hurried back to Mother, but not him. He caught something on the wind, a scent, something strange. A tree...a tree was...moving? Hm, Mother and Father never said anything about trees that move. If it moved on the ground, Father said, it could be hunted. Father would know; Father was a great hunter. Everyone in the pack was. He turned to look after Brothers and Sisters, wondered if they smelled the moving tree. It was getting closer. That was VERY strange. Nothing in the forest came closer to the Den; everything knew to go away, away was safe. Did moving trees hunt? Perhaps the moving tree couldn't smell the Den. Stupid tree. He would hunt the stupid tree. He bolted through the forest, quick and graceful and only a little noisy. Did trees have meat? He slowed, listening hard for the moving tree. He could smell it, oh he could smell the tree but it was quiet but the smell was moving so fast now and it was close! He dropped to his belly, his long, sharp ears pricked up, fierce teeth bared in a silent snarl. He was ready. He'd hunt the stupid tree, and it would learn not to come near the Den. He waited, waited like Father taught and tightened his legs. The tree walked into view, short and spindly and--wait. It didn't look like a tree. Trees didn't have legs and paws. It looked like a bear. And it moved like a bear. An angry bear. Oh, no, Mother told him to stay away from angry bears. Would it notice him? Could it smell him? He crept backward, low on his belly, away from the angry bear that smelled like a tree. The angry tree bear walked on, paying him no mind. He leapt back to his legs and sprinted back to the Den, eager to tell Brothers and Sisters and Mother about the tree bear.
