Toei only animated that one because they were forced to for it to make sense to viewers why Wapol was in reverie. Them not animating the rest baffles me because the anime has really bad pacing issues which would be helped by animating cover arcs and expanding on them instead of making up random filler every once in a while. I cant wait for Enel to come back so they can cram the whole moon cover arc into one minute so it makes sense in the anime.They did a quickie version of Wapols Omnivorous Rampage when the anime hit post-Dressrosa and were highlighting the Reverie lineup.
(I don't know where a version with English subs is, though I doubt they're necessary for this one).
