is one piece episode 387 filler?

After their brief initial run-in with the Flying Fish Riders, the Straw Hat Pirates begin to plan their rescue of Camie's fish-man friend. Luffy is excited over their flying fish.

Usopp asks Franky to move the cannons up to the deck so they can shoot down the flying fish. Camie is worried about "Hacchin", but Pappag says she should worry about herself, since she's the one the Macro Pirates are after.

Back at their compound, Duval tells the Riders that he aborted the attack because he wanted to kill the man that ruined his life himself.
