Imagine yourself going to the leader of your people and explaining that your plan to build the big new “calendar” is to move the giant slabs of rock using the grease from every pig on the island.
That is a lot of bacon and fat-back.
I don’t know how they got the rocks there. I am pretty sure the “let’s kill all of the pigs” plan was not used. Maybe to slip them into place—not to move them very far across a rocky landscape.
Great, now I'm hungry for a BLT.
