Big shiny rock-wheel make Ugh rich. Orange hair-chief say change. Big shiny rock-wheel still good? Ugh not know.

Big Shiny-Car Tribe make many zoom-zoom rock carts with fire-rocks, not smelly rocks. Zoom-zoom fire-rock carts sell much good, but maybe not much longer. Big Chief give shiny rocks (seven five hundred shiny rocks!) to tribe members who buy fire-rock carts. But moon change soon, shiny rocks gone! Maybe tribe not buy so many zoom-zoom carts then. Uh oh. Big Shiny-Car Tribe sad. Big Shiny-Car Tribe say fire-rock carts very good, much fast, not hurt Earth Mother. Other tribes make fire-rock carts too now, much fight for shiny rocks from buyers. Big Shiny-Car Tribe must make best carts, or no one buy. Big Shiny-Car Tribe need find new way make carts good, even without shiny rocks. Oog, mammoth hunter with big club: "Me see many fire-rock carts zoom-zoom past cave. Much quiet, not like smelly rock carts." Borga, rock painter with many colors: "Me friend buy fire-rock cart. Say much fast, much smooth. Me want one too, but need more shiny rocks." Chieftain Rock Smash, leader of Cave Rock Tribe: "Fire-rock carts good for tribe, good for Earth Mother. We hope Big Shiny-Car Tribe find way make good carts, even with no shiny rocks from Big Chief." Story by Thorg from Caveman Talk Fire, on the scene.
