Limpet Rocks are a naturally spawning objects in the Shipwrecked DLC. They are common in Beachbiomes and yield one Limpets each. They can be also mined for Rocks and Flint. If the player does not mine them, they will replenish themselves over 3 days, making them a good food source.
During Hurricane Season, Seagulls will visit land and pick Limpet Rocks for food. During Dry Season Limpet Rocks can wither, thus stopping Limpet generation. The player must then apply Seaweed to the Limpet Rock for it to begin producing Limpets again during Dry Season.
