lol xD .. that's not the name of the event, it's Fishing Buddy .. and the ninetails event, i thing you're talking about the Tailed Beast Board ..

Anyways, yeah, there's a possibility that the said event will be available again in circulation, i think based on the feedbacks from the community .. Just like what happened with the Fateful Choice event where it vanished from the circulation but with the demand from the community, it came back again in circulation, tho sometimes it's just for 2 to 3 days ..

Ah yes, i remember seeing it in one of memo's or kaizer's video on Youtube, just remembered it when you mentioned the paper nets .. Tho i never tried it in-game since, they haven't put it in circulation since i started playing this game and that was around 9 to 10 months ago ..
