i like the shark idea

if the format is the same, fishermen will get in the ocean to catch fish

either as an event, or some other function of the game a shark could be spotted, and all the fishermen clear out of the water for a certain amount of time

i'd like to see a bigger farming plot tho

maybe they can have a little garden inside to start with, and an overgrown path leading off screen. there could be a building puzzle, reconstructing an archway, or clearing the pathway, maybe building a bridge over a stream, and on the other side is a large plot of land where the villagers can farm

then the old garden can become a new puzzle, where medicinal herbs must be transplanted and grown, or some such thing
