Dewgong's cry is 00.90 seconds. Which pokemon has the longest cry and how many seconds is it? The reason why i said black in white is because they may have had cry changes so i dunno
Although I don't know the exact length, I know it because the screen stops moving for a while while Jynx's cry is still playing.
Jynx has 2:13 seconds
and in black and white proabibly zekrom and samurott and klinklang
