after leaving the Marewaii Islands, the sparkle lurkers would make nests in places most ponies could not go all along equestria’s coastline, some even moving further in land. their numbers would then, for a short time, rapidly grow, as they adapted to their new environments. The biggest change came in their colorization, first starting as family groups looking different from one another, to individual lurkers developing distinct characteristics from each other. these Lurkers would eventually find their way into pony society, a few going months before the ponies realize that they had made friends with a giant crab pony.
