Econda (a new mob)

These snake-like mobs would like in the Overworld and Nether and spawn at noon only. They could hatch from an egg and grow to be 6 blocks long and have venomous fangs that are only visible when it's mouth is open. It attacks by twisting itself around a mob, disabling their abilities, and biting it. Each bite deals 3 hearts of damage and inflict poison for 5 seconds. It can be tamed by leashing it then feeding it rotten flesh. When tamed it will never attack you again and attack all hostile mobs within 7 blocks of you. If multiple eggs hatch in the same place then the hatching speeds up by however many eggs are in one block. The eggs cannot be crafted, only traded by traveling merchants and found in suspicious sand or gravel.
