Sandmaker

When my ten-year-old was a toddler, he used to watch a show called 'Splash and Bubbles' about a little troupe of fish that explores the ocean together. One day they met a parrot fish and while they were all talking, one of the main fishies snuggled into the sand and said, "This sand is soo soft." To which parrot fish replied, "Thank you!" Then the parrot fish explained how it chews up coral and then poops it out as the the softest sand--a fact I will never, ever forget.
