There was a second call, Right as they began the attack on the arena @ 16:44,There was INK's call, the one we all know so well, But then, right after that, there was a second call, this one was different, it was more hollow. I don't know if there is a significance to this or not, it might just be that Kc and Co had to fit in all the zombie growl winners, but maybe there is a difference between the colored one and the marked one
