This irreverent, sometimes raunchy animated feature by Picha takes an acerbic look at a hypothetical "missing link" by the name of "O." Born somewhere around 200,000 B.C., give or take a few generations, "O" was a reject because his pink and unbearded self was a mite too intelligent and off-beat to the rest of his hairy clan. So a friendly brontosaurus and smart-mouthed pterodactyl bring up "O" as though he were their very own. While roaming through hill and dale to find his tribe once he is an adult, "O" comes across all the weird creatures that will eventually contribute to his understanding of the world -- and the beginning of what passes for civilization is launched.
