Can someone identify this song?

[SouthPolePengwin]

I was watching videos on YouTube when I heard this song which I know I've heard many times before. But I can't name it

Here is the link to the video:

(Also the music I'm looking for starts at 00:22/03:35 and continues in and out throughout the rest of the video.)

Thanks in advance!
