Expected behavior

Have Sponge be added to the Fisherman as a potential drop. Say .01% to .1% chance.
This will help with long-running servers where the ocean monuments have been depleted. As sponge is not a renewable resource, new and existing players will not be able to craft or use sponge items.
This will also allow a random drop for those servers where ocean biomes are rare, or perhaps non-existant. (as per cave colonies)
