I guess I was pretty lucky this time around; took me 3 tries. TBH, I had/have tons more grief trying to 3-Medal campaigns 10-12. The odds are at least double in favor of this event compared to 10-5, since the bottom route splits the group up one or two more times less. Fortunately for us, the enemies didn't get any stronger from ?-4.

But when you finally hit that gawddam boss, you're gonna enjoy the epic promo-music that plays as well as the special attack that puts the gawddam annoying 50% Caterpillars to shame (cough99%guaranteeddamagecough).
