Usopp Vs Perona Episode. Of course the English subs on CrunchyRoll just say Usopp but the Japanese voice actor. Both took half a year to finish.
When the camera panned away to reveal Usopp had lied about his Big Bang Star attack and that he had actually caught Perona with a sticky mess to ensure he had her trapped that was a stroke of genius. Usopps fight against Perona was basically a reiteration of Luffy versus Enel. Usopp does not believe it and continues to run as Perona creates more mini hollows.
When hes bluffing his ASS out of a real fight with his inflatable Usopp Golden Pound 10-ton hammer.
Perona is highly annoyed at the alter ego as Usopp turns to run away again. Not ready for how GODDAMN FUNNY it was going to be. We celebrate the comedic and casual side of the One Piece series. He hurls a projectile full of cockroaches and hits her with a fake 10-ton hammer which does the trick.
