For a while I was unhappy because I had the little person walk all around the outside but I couldn't figure out how to get them onto the inside pointing the other way, and shouldn't that be possible? Isn't that the whole point?

And then it hit me: the figure-8 does that! The little person doesn't have to walk all around and up a tube and through a hole like they do on the regular immersion, they can switch anywhere they want!
