Siblings. Rocky had quite a few of them.

His short life had been spent mostly with his littermates, his fathers and the den that they were born in. he had seen and met some others that called themselves his half-siblings and it was pretty cool. he wasn't really sure how that worked, how someone could only be half of a sibling, but it was still cool!
He had seen one of them a few times and she was his favourite half sibling! Goldie had taken him out of the den and exploring and swimming and they'd done a lot of cool stuff together! Rocky loved her and she was awesome.

The puppy would currently be sitting on the sand of Barracuda Bay, staring at the waves that gently dove onto and off of the shore. It was something he'd seen a lot but it was always super pretty. His ears would twitch slightly as he heard something behind him and he'd jump onto his paws, twirling around with a bright smile.
"Big Sis!" He'd yip happily, bounding over to her and attempting to nuzzle her. "How ya doin!"
