Brighter Day 2 HELP!! (3rd carriguine?)

[XxSJC16xX]

hey all,
So i can't beat this mission and the reason being is because a third carriguine has been spawning and it has like every buff on it. When i previously tried to do this mission, sometimes he would spawn and sometimes he wouldn't. I don't get if theres some trick to make him not spawn, but i've seen videos where it doesn't spawn in order to get under 11 minutes. HELP PLEASE!!!!!!!!!!!

Thanks,
SJC

Just an update. Seems like if you complete it as fast as possible that the 3rd carriguine doesn't spawn. Gravity Dance FTW!!!!! Finally got my 15* wep.
