Cherry-Nose is kind of grumpy and as such, he prefers to be alone. Not by his own choice, mind you.. It's more of a learned thing since he doesn't get along with most wolves. So, what better job for him to have than Lead Scout? There's not much for him to do for Scout Apprentices other than tell them not to get themselves killed. And he can do that very well and very menacingly, might I add.
