is one piece episode 7 filler?

Luffy knocks Boodle unconscious to prevent him from injuring himself further in battle. Buggy fires a Buggy Ball at the group, but Luffy deflects the cannonball using his rubber body, firing the projectile back at the Buggy Pirates.

Buggy's men are decimated by the attack, save for Buggy himself, who had used his subordinates as human shields, and his chief of staff and acrobat, Cabaji, who had used Richie as a shield. Cabaji offers to battle the group on Buggy's behalf, and Zoro decides to duel him one-on-one.
