RE: Outhouse

The island just isn't that big. A full village can hold 115 villagers. There will be poo everywhere.

In VV3, an outhouse could be like the fire in VV2, and cleaning the outhouse every 9 hours (carrying the poo with shovels and tossing it into the ocean?) could be like building the fire every 9 hours in VV2.

And too much poo in the ocean could be like algae, with a puzzle needed to solve it.

In Star Trek, I never saw any bathrooms. I don't think bathrooms make for very good TV, and likely the same applies to computer games. Although outhouses may mimic reality, building outhouses and shoveling poo in a computer game will likely drive away more customers than attract them.

So my new theory is that virtual villagers make virtual poo, which carries no disease, has no odor, decomposes immediately, and is an excellent fertilizer.
