I'm glad they've fixed the audio on these videos. It was annoying having the sound coming only from one side. It was weird that they didn't have it right to begin with; it seems like something basic for a professional video.
On the latest video - Sam seems like an odd choice to be interacting with kids. (And the boy he was talking with didn't seem too engaged - he wasn't looking at Sam - though that could be coincidence.)
And what's the red thing that looks like its on Bubba's nose?
I think it's the end of his tail, and just happens to be perfectly lined up.
