Gilded Bay this is our party, we can do what we want

Dash reached down into the tidepool, mouth agape. From the look of its shimmering image on the surface of the water, he was convinced that he was about to fish up the biggest oyster known to wolfkind. This was what he had come for. The was why he had gotten up at the buttcrack of dawn. The early bird catches the worm, and all that.

He brought his head back to the surface, his prize triumphantly clutched in his jaws. Oceanwater streamed down his neck and chest. He spat his prize into the sand, and then he cocked in head in question. It looked like no living thing he had ever seen. It was almost perfectly round, and sort of hard on the outside, except that it was all wrapped up in long, sodden fur. It looked like some weird hybrid between a rock and.. like a beaver, or something. 

Dash nudged the coconut, and it rolled down the beach a ways. Maybe it was some kind of shellfish? Should he try to crack it open?
