Add the possibility of transformation of the axolotl in ambystoma

In real life, the axolotl is the larva of ambystoma. Ambistoma is a lizard that lives on land, if the axolotl does not like to live in water (due to predators or other circumstances), then it goes out on land and becomes an ambistoma. In minecraft the animal may not die for five minutes and turn into ambystoma and live on land. I would also like to see the black colors of the axolotl.
