is one piece episode 87 filler?

Chess lets Wapol know of the flag on top of Drum Castle. Luffy uses Gomu Gomu no Pistol on Wapol, sending him flying, but he is rescued by his subordinates just when he is about to fall down the mountain.

As Luffy goes into the castle to find warm clothes, Sanji protects Kureha from an afro thrown by Kuromarimo. Kuromarimo keeps throwing afros at Sanji, even though they pose no apparent danger, they stick to their foes by static, so when Chess fires an incendiary arrow, the afros start a fire.

Luffy borrows Nami's jacket and with the help with Sanji, they throw an attack at Wapol.
