Easy Shellshock Achievement
To unlock this Achievement you need to bounce off a falling turtle. This can be done easily in the light world by simply using your dash attack (X button) on it like you are attacking an enemy. This will make you bounce off the turtle which unlocks the Achievement. Just jumping on top of the turtle will not work.
