is one piece episode 885 filler?

Vivi, Rebecca and Shirahoshi discuss their experiences with Luffy. Dalton and Kureha appear at the Levely from the Sakura Kingdom, but also Wapol, who had taken over another kingdom.

Vivi remembers her adventure on Drum Island. The Straw Hats previously stopped by Drum Island because Nami had come down with an incapacitating disease.

Drum Island was ransacked by Blackbeard before the Straw Hats arrived only to have their own king, Wapol, abandon the country. After the Straw Hats arrived, Wapol returned, and Luffy had to prevent Wapol from taking back the throne.
