I assume that after they ate all their fellow cannibals, the last guy simply starved to death. Cannibalism doesn’t work out that well for propagating the species, especially since babies are so finger-lickin’ good.
Colonel Sanders had a whole different menu in Fiji, and he was quite successful.

L. Gemser has a special place in my heart.
Her cheekbones, her impeccable body, the fact that she was the costume designer for Troll 2 “They’re eating her… and then they’re going to eat me… OH MY GOOOOOOOOOOOOOOOD!”
