Baby turtles in cage( on the shore ) when they are on the sand causes severe lag(turtles don't move around but stays still on sand) .

If I attract them into the water(still inside cage) the lag will be gone.

If I stop attracting them with seagrass then they go back on sand and start causing lag. 

If I attract them into the water and block the way back to sand the lag is gone for good.

I found out the lag when I try fishing there. fishing slows down alot. mobs moves slow or stops for a while.

I copyed the world into android machine and it seems that lag is gone but I'm not sure as the machine can handle pretty well since the world is newly generated.
