At least I think that's a clarinet. My entire musical endeavors involved the plastic recorder in like 2nd and 3rd grades, and like a minute of piano lessons which I immediately gave up about a year or two later. So don't trust my judgment on which instrument is which.
But who cares about that. All I see/hear is the Penguins theme song, righteously played on some thing. Too bad this isn't longer...that's my only critique.
