rollin rollin

A man's head is superimposed onto a cartoon character riding a large, blue, crystalline creature across a blue background with floating ice shards; the character and creature move from left to right, then the scene cuts to a different man's head on the same character, who then moves from right to left, before cutting back to the first man's head as the character moves left to right again, with the text "KEEP ROLLIN' ROLLIN' ROLLIN' ROLLIN'" at the bottom.
