1. the turtle is just a drawing 2. thus, the turtle is no living being => does not possess life 3. thus, the turtle is in no danger of losing it's life 4. if there is no danger for losing life, there is no need for saving => the turtle is already saved.
It might save the turtle. You could calculate the speed of the weight, the distance between the plus/minus sign and the turtle, and compare the masses. Maybe. I just made that up. But that would take too long anyways.
