I wonder if before the deserts became a desert that Nibblesnarfs ancestors used mud or regular water before transitioning to sand.
That is actually a solid theory, and one posited by many different scholars in the research field! It already has been commonly accepted that Monsters evolve at a faster rate than more common animals, thus many researchers have presented this idea before as to why and how species that seem otherwise aquatic have adapted so readily to such arid conditions. Such ecological shifts would also explain monsters such as Cephalos, Delex, Balahara, and even the Mohrans. However, this is also a topic of much debate, and no conclusive papers have been published as of yet. Opposing arguments by other researchers propose these are simply examples of convergent evolution of such body plans in the environmental conditions of sand seas. It is a very complex and frequently revisted topic, hence why no conclusion has yet been reached.
