Seagrass is an underwater plant that players can collect with shears. It serves as food for turtles and can be used to breed them. Additionally, it can be planted on most types of underwater blocks, providing an aesthetic enhancement to aquatic environments and serving as a habitat for fish. It also plays a role in crafting, as it can be used to make turtle shells, which are components for brewing potions of the Turtle Master.
