User blog comment:Yesxirb22/What do you think of Carrot's role will be?/@comment-208.44.214.45-20171027160654

Barrelman. Er... barrelwoman... Barrelbunny?

It's a naval term for the guy who sits in the crow's nest.

Also, some people have stated that Carrot can't join because she doesn't have a troubled past.

That's only as far as we know so far. We didn't get Robin's dark past until years after she joined. And we didn't get all of Luffy's past until much later.

If Oda revels that Carrot's parents are dead or something and she was pretty much raised by all the other minks, I would not be surprised. Though I think losing Pedro counts as traumatic enough.
