I’ve found out that you can collect Tidepool sculpin micro fishing. I can collect bits and pieces of seaweed and collect shore crabs for “bait”, and im aloud to collect periwinkle snails, and maybe even the shrimp I was talking about. In certain places, I can collect rocks, small ones, that could have hitchhikers including anemones! I can not keep live sand dollars. I can collect limpets, I believe, and maybe even the Derby Bryozoan!
