Pygmy Dragons were released on July 15, 2009, alongside Albino, Cheese and Ochredrake dragons. Since their introduction to the cave, they have been updated to display gender dimorphism. Like all , their eggs cannot be bitten by Vampire Dragons and they can only breed with other pygmies or Pumpkin Dragons. When sorted by Breed, Pygmy Dragons are listed as "Pygmy"; as of August 14, 2016, they no longer sort above all other pygmy-type dragons.
