@vincentsautter Apparently it's a very specific type of frog that lives in the area around Hollywood, meaning that a ton of the frog noises captured in film/used in soundboards were that. It was a major wtf moment when I read that
@vincentsautter Oooh, thanks for linking!
@aslevjal just read up on it, there was a sound file too! Pretty cool, even though it still doesn't quite sound like ribbit to me https://www.englishforums.com/English/TheFrogThatSaysRibbit/ndwhn/post.htm
