Grass Turtles

Hi

I am playing minecraft for almost a year and a half but the idea of making a turtle sounds really cool!.

But i have another idea for another turtle for minecraft, The Grass Turtle, The grass turtle, He can spawn if a Turtle is steping on Grass Block, Dirt, Coarse dirt, Leaves And Log for 1 minute he will turn into grass turtle, The grass turtle have 20 hearts of life but he will be more slower Then a regular turtle And he Can change back to a regular turtle With Wet sponge But he takes damage from water or water in Cauldron, When he dies he have 5% or droping a difret kind of sapling 0so if there is 6 types of saplings in minecraft he have 30% for droping sapling, 5% to drop apple and 55% for dropping dirt and 10% for droping apple And evry time the player attack him and noy one shoting him he will attack you and if there is more grass turtle nearby him they will atack to but they do half a heart of damage beacuse the high health, Also they look like turtle but with oak sapling on the top a litle bit bigger then normal turtle and looks more dirty, Also When they grow up from baby to normal grass turtle they will drop a spacial dirt called the crops dirt and they will grow up crops with use on him with hoe 3 times more faster then normal dirt and you can craft with 1 crops dirt 9 bone meals and you can breed 2 grass turtle with azalea leaves.
