Wasn't the Sea Scorpion King the founder of that Dynasty?
The Princess Anemone figures in the story somewhere, too.
It is quite apparent, with all the varying tales of the great flood, that there were fabricators back then just as there are today. Folks who cannot bear to hear the unpolished truth. References to Sea Kings and pebbles thrown over shoulders are the fanciful tales that, today, have been replaced with theories of evolution. Some people simply can't get their story straight. Business as usual.
