Breeding turtles is a cute and fun experience, but the cuteness and the breeding itself aren’t the only reasons why one might want to make Sea Turtles breed. Baby turtles grow up into adults over time (you can feed them 10 Seagrass items to speed things up). As they turn into an adult, they will drop a scute. Gather up five scutes, and you can craft a turtle shell, which you can put on and wear underwater to trigger the water breathing perk. Turtle shells can also be used to craft a potion called “turtle master.” This potion will grant the player Slowness IV and Resistance IV.
