There's a fun little children's song that has a variety of versions floating around. The song is known as "The Little Green Frog"

When I first learned the song as a teenager it went this way:

"Barump went the little green frog one day
Barump with the little green frog
Barump with the little green frog one day
And his eyes went Bonk!Bonk!"

I later heard it on a children's program while I lived overseas and the following words won the day:

Mmm mmm went the little green frog one day
Mmm mmm went the little green frog
Mmm mmm went the little green frog one day
And we all went mmm mmm ahhh!!

But we know frogs go ladedadeda
ladedadeda ladedadeda
We know frogs go ladedadeda
ladedadeda ladedadeda
They don't go mmm mmm ahh.

(Motions--close eyes, then stick out tongue, then sing "went the little green frog"/at the end of the first part--close eyes, stick out tongue, shake face with tongue out/clap before each "ladedadeda"/last line same as last line of first part)

Here you can communicate to a child that the only time appropriate to stick out your tongue is when singing this song.

And now to the point of the story. Not long ago I was reading with Little Bit (my youngest) who is learning to talk. The book was about colors, and on green there was a big picture of a green frog. I asked how does a frog go? fully expecting 'ribbit, ribbit.' And you guessed it, she said, "ladedadeda."

After all we all know frogs go "ladedadeda."
