Smaller troublemakers may end up inside the beach's anthros. (Greg the polar bear could manage a bigger one, but he's 8 1/2 feet tall). Larger ones are usually eaten by various other large animals. Dolphins who visit the beach vary in size a lot and unlike real world ones, their stomachs are huge. It's a saying on the beach that one dolphin (or sea lion) fits neatly inside another, and not just in the sexual sense.
