It's a bit hard to tell what's going on in the MV; the members are freezing their tails off in a life-sized cooler, there is an adorable goose in a uniform, and a girl is seen crawling toward someplace...then the camera pans to ASTRO making derpy faces. 

Yep, I'm officially puzzled. But the teaser does make me look forward to the full MV! How will all the above things tie together (if at all)?
