Performer(s) Appeared in One Million B.C., called O.M. for short, is a character from the Rankin/Bass television special Rudolph's Shiny New Year. He is the representative of the island that holds the distinction of being one of the oldest in the Archipelago of Last Years. He is an excitable cave-dweller who spends his time with the island's local dinosaurs (despite the fact that humans and dinosaurs never actually coexisted together). His philosophy is that if you laugh, you'll find that it's raining sunshine.
