example: Froslass has a 01.75 second cry and i know that isn't it. The reason why i said black and white is because the cries may have changed but i dunno
>I've heard a lot of cries, but I'm pretty sure Snorlax has the shortest. Yeah Snorlax and Jigglypuff both have a pretty short cry. I think Snorlax just has a tad bit shorter of one.
So, Snorlax. No idea how long though.
