One thing I fail to understand is Death bull says he have two scythe to increase the chance of hitting them but he only used one when those really fast cows "attacked" him. Is it a miss?
Perhaps he didn't pull it out at that time because he didn't really want to show it the other two reapers...? That, and to show them how much of a struggle it is to try to hit them with just one.
