Stone Circle going on an adventure

A voice came from the other side of the stone he'd been talking to, and Charles blinked his eyes as he received a 'hello' back. Then his smile broadened, happy that the stone was talking back to him. He didn't actually think too much of it; Charles had a vivid enough imagination, and this world was all about him, of course, so it made sense everything he'd talk to would find their voice and talk back. Words were still something he was learning, however, and they did not yet hold the same gravity they did to the adults all around him. He was mostly still shouting things and seeing how the world reacted.

A wolf stepped into view and Charles looked up at her. He recognised his name, and repeated, Hi! to the wolf, then the part of her sentence he had understood in confirmation: Char! Yap-yap! Though it was likely he'd have repeated his siblings' names if she had spoken those, too. Charles looked up at the mother stone and walked further up to it. He put his front paws on the stone and looked up with interest. What'ssat?
