At this point the Nomlights became an ubiquitous presence in the near-surface seas, staining their homes with the brilliant blue-gray of a urinal cake. The species had become so prolific that some populations grew tired of the hustle and bustle of ocean life and moved to the beaches. Any other cell ending up on the balmy shorelines of Dingus and Oofle would simply rent a resort apartment, but these Nomlights are not like those stuffy old coots - they instead adapted.
From these populations came the Drynoms, so named for their greater distancing from the waters, though still within the surfline - they’re not that dry. To protect from desiccation, Drynoms developed large vacuoles and tight cell walls to keep their precious water within them.
While their ocean-going ancestors merely congregate with abundant nutrients, the Drynoms exist in much closer company. Individual cells are clustered together in the tide, held by supports of cellulose. Consequently, this causes them to form colonies expanding many centimeters in width, with many colonies blanketing any well-watered surface on the beaches they inhabit. Within only a few decades since their evolution, the beaches of many landmasses have turned from sandy beige to bold, light-nomming urinal cake blue.
