When I was six, some bright spark decided to repaint the school swimming pool. The blue background was probably necessary to disguise the yellow water, but it was a pool for children, so they didn’t stop there.
Soon a dozen colourful starfish and octopuses crawled across the pool floor. I was as happy as you can be about cute creatures painted in a pool two degrees above having icebergs. (Actually, it was probably only the urine content that kept the pool from freezing entirely.)
Then there was the shark.
