Hi Lyndon:
I will find out when I am home today or tomorrow. Boy, this is cool, having this web-support. The tower is actually a series of towers that look sort of cstle-like in a space-black sort of way. You use the double x superjump motion to get to the top of the towers. And only if you change into the ja-ja guy can your jump even get close. But finally, there's a really tall tower that you can't quite jump high enough, even if you get a running start. To get past, somehow you do something that causes the tower to shrink to half size and then it's easy...
But I'll find out the chapter.
Thanks,
Joey
