Ooooo, they are all grown up! Turtles have been a part of Minecraft since 1.13, they are cute and you can get a cool helmet if you're lucky!
However, they can now grow into giants, hostile mobs. Giant turtles like to lure their prey using palm trees and sand castles, then will jump out of the sand to catch them unaware.
This update also adds a new Turtle Shell shield and coconuts that players can use or trade!
