Just look at Momo's future scabbards go! They work well together.
Also interesting that Momo doesn't turn into a perv over Yamao. Makes their relationship a bit more special. Shows Momo was willing to ride around in Yamao's cleavage surprisingly not because he's horny, but because he actually trusts her. Seems like something Oda would have taken into consideration for their dynamic if it is gonna be a long term thing.

Meanwhile the anticipation builds and builds for the Carrot fight. It's the only battle Oda's completely hidden and chosen not to reveal any insight about. All other characters Oda gave an update on. We've seen:
Roof piece
All the straw hat vs
Chopper making medicine
Drake vs Apoo
Marco vs King (Queen suspiciously absent, likely after Sanji)
Jack
Bepo
Wire
Hyoguro
As you can see, Oda is willing to give panels updating us on the battles of completely irrelevant characters like Wire in Kids crew, yet it seems he's intentionally avoiding giving the slightest spoiler into how Carrot's fight is going. The reasons for this could be huge for Carrot. Bottom line is that at this point it seems like Oda definetly has a special plan for the fight that he believes warrants him hiding that single fight out of everything happening in Onigashima.
