海草 is an item that can be found in the ocean by fishing during all seasons. It can also be foraged along the bottom shore of the tidal pool beach, across the bridge that needs repaired.[1] There is a 41% chance to catch Seaweed while fishing in the deep-sea submarine ride at the Night Market. Several Crab Potfish may produce 1-3 Seaweed in a Fish Pond when the population of the pond is at least 1.
