This egg was only available in Egg Cave's Cash Shop Park for March 2012.
Ranfil eggs are generally found floating on top of small water pools or slow-moving streams. Upon removing them from a moist environment, the eggs shrivel and disintegrate.
Ranfils are among one of the most studied and researched creatures in Ark. In samples taken from Ranfils, the Science and Research Center in Ark City has found many similarities between Ranfils and the other eggs and creatures spotted around The Mysterious Asteroid. This has lead scientists to believe that Ranfils may have indeed come to Ark via The Mysterious Asteroid. Mysteriously enough, Ranfils do not appear around The Mysterious Asteroid, however.
Ranfil, unless reasonably aggravated, are peaceful creatures. They have a vegetarian diet and roam the wetlands and swamps of Ark.
