Thanks!

Yeah, you don't get perfect control of them. :-) The intention is that you use FOLLOW to lead them far enough away from the spikes, then tell them to STAY. But they wander around a bit where ever you leave them - they're monsters! Maybe I should have called the STAY behavior NONE or something like that?
Anyway, thanks again, I really appreciate the feedback :-)
