IF YOU WATCH THIS, YOU'RE LIKELY TO GET SEIZURES! WATCH AT YOUR OWN RISK!
Its will never be completed if you watch whole Pokemon series without this episode.
Tips in watching , PLEASE CLOSE YOUR Eyes during the explosion part. open your eyes only when you hear that its should be over.
[Personally I am no problem at all after watched the episode as a whole. ]
On 1997 Dec 16, This episode had been broadcast in Japan and caused 685 persons hospitalized due to Seizures effect. Yet This episode had been banned worldwide and Pokemon had been stopped to be broadcasting for about 1 year long in Japan as well.
