Blizzard frowned when she saw Wind's pups. They were smaller and weaker than Koi's pups had been. They were both male. One was white like wind with his father's red markings, and the other looked just like his father, with black eyes. After careful testing she determined the pup that looked like Wind was stronger, and with sad eyes, she chased the other away.
Wind named the pup who stayed Stain, because she said he was stained with his brother's blood. If he hadn't been born, his brother would have probably stayed.
Stain didn't have any siblings to play with after his unnamed brother was left in the wild, but Stone and Shade took a liking to him. They were adolescents when Stain was born and they didn't have much to do other than cause trouble, so they didn't mind playing with Stain who didn't have any siblings left to play with.
Whilst running around unsupervised, Stain wasn't paying attention and got his paw stuck in a deep bunny tunnel, causing him to trip and injure his leg. He will walk with a limp for a short while, but is otherwise unscathed. For now. Oh no! Stain gained a small injury and suffered -1 HP
Your pup, Stain, got a little too cocky while trying to play around with one of your scouts. After boasting that he would be the victor of a tussle between the two, Stain quickly got put into his place. Your scout looks sheepish for causing harm to the pup. Clearly, they're not pupsitter material. Oh no! Stain gained a small injury and suffered -5 HP
