I'm looking for a certain HxH OG anime movie or episode

[Formerly Black Trash]

It focuses on Hisoka and the Phantom Troupe
I don't remember anything else about it but I only seen a clip
I think it had a purple tint
I really thought it was a movie

 

[Neuromancer]

Might be movie 1. That had a lot of Hisoka and Phantom Troup stuff
