Quote #10
The first shoal of Shrake is believed to have been created as a revenge against Muggle fisherfolk who had insulted a team of sailing wizards in the early 1800s. From that day on, any Muggles fishing in that particular patch of sea have found their nets come up ripped and empty owing to the Shrakes swimming deep below. (27.4)
There's a lesson here—never insult a wizard. Or anyone who might be a wizard. (Better yet, just don't insult people. It's not nice.) Looks like these Muggles got their comeuppance in the form of Shrake-shaped holes in their nets.
