This is so well written! You presented counter arguments (Momo) and excellent support for your own. I was especially surprised by all of the connections between Vivi and Carrot! Thanks for the good read; it's a nice way for me to spend a sick day.
Great theory, outstanding effort man ! I already saw pudding joining the crew more likely than carrot, but you brought out very solid evidences which supports it more . Pretty sad about that carrot idea though, I liked her more than pudding, she has a cute character, lovable and funny, but puddings identity disorder is so cool ahah, she may be really fit to join . Nice work :-)
The most unlikely idea that Carrot will join is that her initial letter name is the same with Chopper : C. So far there is no SH crew with same initial letter. Carrot will probably the same like Vivi, Rebecca, Conis, Shirahoshi, and any other supporting female ally.
A very interesting theory with a cool twist. I personally find Pudding for Nakama unlikely despite the fact I'd like it because I ascribe to the theory that Pudding saw the future when she was talking about Sanji during her introduction.
Carrot is lovely, and it would be sad if she doesn't join the crew, but... you know what, you've been making a lot of cool theories recently and I think your deductions are very well articulated. Let's see what the future holds :D
