What most people dont seem to realise is that fizzys legs are curled up most of the time, which doesnt reveal how high she can actually stand, if she had her back 4 legs fully straightened and her front two off the ground to her tallest possible extent, she would stand at just under 4 feet tall, though she cannot move when like this without risk of severe injuries such as sprains or even broken body parts, even like this she stands at about 3 and a bit feet.
A neat thing about crustaceans and insects...
