I had never seen the second one, with the pool. But clicking through to the YouTube page, I see that it never aired.
I don't remember the "long version" with the intro sequence of the first one, either. There must have been a 60-second version and a 30-second version.
I also did not realize that ad was made by Will Vinton studios. I used to work with a guy who had formerly been employed by Will Vinton animation studios. He ended up going to work for the post office because it paid a lot better.
