Swimmer - New Ancient Mob

The Swimmer is a new ancient mob that looks like a crocodile with a sail on its head. However, it would be a passive mob that can be found in a similar fashion to the Sniffer. You can ride the Swimmer. It will try to buck you several times until you tame it (similar to horses). The Swimmer is slow on land but moves slightly slower than boats in the water. The Swimmer has high HP and will absorb part of the damage the player takes from hostile mobs while you ride it. The Swimmer can also be bred and healed using raw pufferfish, because pufferfish in the real world have existed for millions of years. The Swimmer only drops a few experience orbs
