A snowboarder interacting with a large, cartoonish yellow character in a snowy mountain setting.

The video opens with a snowboarder in a snowy mountain landscape, with a large, cartoonish yellow figure resembling a gorilla or yeti standing behind them. The scene transitions to a close-up of the yellow figure, which is wearing ski goggles. The video then shows a graphic with the text "MTN. BUM" and "by Sun Bum" with the yellow figure below it. The pacing is quick, with rapid cuts between the live-action footage and the graphic.
