I know this question was probubly asked 1000000000 times but is there a way to get bolly and ultrus to stay in one place. Belts don't work for ultres. I've tried that. If somebody can give me some help thanks!

Bolly can be held more or less in place by the use of belts, as seen in Red October. Uterus... not so much. :\

I know but is there a way to keep ultres in one place

He just said no.

Red October wasn't the only one!
I used that concept for a boss battle in my Thieve's Conspiracy levelpack before knowing it existed! (I downloaded the level only recently. Pretty cool.)

About the Uterus thing...
No clue there. : /
