Ha, get the boy on the computer and reading then!

It looks like the tube on the right goes right up to the top. Depending on how small he is he could probably climb up the decorations. I had a green yearling escape and climb right up some blinds (still have no bloody idea how he managed), and my supposedly-terrestrial fatty cuban can jump up a good ~2 feet if he really wants up somewhere. So don't be surprised where the guy ends up, lol.

I don't know if you have any vendors that sell it at reptile shows, but if you can track down one of those I usually get big grapevine "branches" for $40-$60, depending on size. Store bought is a little ridiculous, yes. Mostly cosmetics though, so if your brother doesn't really care about the decor it shouldn't matter.
