Field boss spawn time/rate

[BloodFigther]

Hello, iv been curious about the spawn rate of the field boss in the saphire pool

I wanted to farm the essence's of King kaari and waited 1-2 hours for him to spawn.

You have to kill the fish monsters to make him spawn. ^_^

I believe very specifically its the turtles.   I remember one of the little lore books mention livers, and that either the turtles or crabs didn't work.  So I'd do the turtles to spawn the field boss behind the plogstead.
