On fishkind isle, in tavern, we can find heavy fishkind's recruit. He require "Prostitution service". Well, we can abuse him 24/7 to fill ourself to... I think you know, what i mean. It's realy cool method to farm children (and fishkind, and deepone)

So, i think, better way - we need rebalance him. Added, somethink, cooldown for "expand time", ot other... 

theres an easier way to get fishkind spunk just go to the arena theres a fishman you can prostitute to leave and come back into the arena all without having to go to fishtopia
