is one piece episode 37 filler?

Despite her pleas, Nezumi seizes all of Nami's savings, finding the treasure buried in the orchard and keeping a portion of it for himself. Nami realizes that Arlong sent Nezumi to seize her wealth so he would not have to forfeit the village.

After Nami attempts to fight back, Nezumi shoots Nojiko in the back. While Nojiko's wounds are treated by a village doctor, Nami confronts Arlong.

Arlong argues that he did not break any terms of his promise by sending Nezumi after Nami's treasure.
