Axolotl

After Zenith wanted a twin, he converts his friend Reepe into another Zenith! The two Twins will have a great time together, especially considering the fact they are identical!~ Originally on fA: https://www.furaffinity.net/view/43984828/

Unlike other amphibians, Axolotls never undergo metamorphosis and spend their entire life in a larval state. That is, unless they spontaneously decide otherwise...
