I'm Just Curious

Lulu is spanked and sent to bed, where she sings the title song. Later, a chicken hawk tries to break into the family's henhouse, raising Lulu's curiosity.

Because the uncredited song takes up half the cartoon, there seems to be a rather abrupt transition after it is done. Are we looking at Lulu singing the song, followed by enough of a story to bring it up to the 6.5 minutes a cartoon takes, or is a very short cartoon about Lulu fending off a chickenhawk eked out with a song?

I found the song not particularly excellent, and as for the story part of the cartoon, I thought there was one good gag.
