Turtle

Turtles are passive mobs that move both on land and in water.

Spawning
Turtles spawn in the Overworld on warm beaches, occasionally in small groups of up to 5 individuals.

Drops
Turtles drop 0–2 pieces of sea grass upon death and 1–3 experience orbs if killed by a player or tamed wolf. When baby turtles grow into adults they drop 1 scute.

Behavior
Turtles swim around aimlessly when in water, and move slowly when on land. When on land, they will generally attempt to move to the nearest water source. They will follow players holding sea grass, and flee when attacked.

Baby turtles are attacked by the following mobs: All three types of zombies, as well as zombie pigmen, will also stomp on and destroy turtle eggs.
 * Zombies
 * Skeletons
 * Wild s and wild

Home location
Turtles have the ability to "remember" the location where they first spawned, which is known as their "home location." Basically, even if they move very far away from their spawn, they will always come back to their home to lay their eggs on any sand block nearby. Baby turtles get their home location from the position of the turtle eggs they hatched from. This means that if you break turtle eggs somewhere in the world and take them to a different spot, the baby turtles will remember that spot instead when they hatch. Turtle eggs only hatch on sand though.

Breeding
If two turtles are fed sea grass, they will mate (which grants a small amount of experience to the player). One of the turtles will then have an egg in its inventory, making its secondary action list of: returning to its breeding grounds, find a nearby sand, burrow on the sand and lay some turtle eggs. However, if fed again, this turtle is able to mate again.

Once an egg-filled turtle returns to its home, it will move to nearby sand. After several seconds of digging action on top of the sand, it lays a turtle egg, which take around 40 minutes to hatch. A turtle can lay no more than 4 eggs per sand block.

The growth of baby turtles can be slowly accelerated using sea grass. Each use takes 10% off the remaining time to grow up.

Trivia

 * With a height of 0.12 blocks, baby turtles are the shortest mobs in the game.
