Sea Serpent

The sea serpent is an optional boss who must be fought to reach Minelantis.

Fighting
In order to fight the Sea Serpent, you first must obtain the "magic conch". It is a shell that summons the serpent. To get this, make a 3x3 1-block deep hole (it has to be in the sand within 5 blocks of the ocean) and put a block of gravel in the middle. Put 1 block of sand on top of this and fill the hole with water. Use bone meal on the top sand block and the conch will pop out!
