is one piece episode 906 filler?

Luffy defeats Holed'em, sending him crashing to the ground, then takes Tama and flees. Zoro, Kiku, and Komachiyo also flee on Speed's food cart.

Speed sends soldiers to chase after them. Luffy gets cornered by angry citizens, but easily defeats them.

He hops onto Speed's back, mistaking her for a real horse. Although Speed is hostile to Luffy, Tama uses her Devil Fruit ability, creates a mochi, and feeds it to Speed, taming her.

Speed immediately begins following Tama's commands, running away and helping them escape.
