How odd... I don't have a simulation saved, but I'll run another one with it in when I get home from college.
I've never been able to get it to move, and the last sim I ran with it (on it own, not even any veggies) it just sat there and duplicated itself, occassionally tieing to another one. I started off with one, and after 9 seconds there was 710.
I'll try and duplicate that again tonight, if I manage it I'll post the sim.
