When i was elementary school student,we student sang this song in music class.....

♪♪♪ Hey!! Teacher!! There is a bridge over there. There is a bridge.....♪♪♪

Over 40 years later.....

I completely forgot the name of this song,but I found out this one by this website.

And one more song.....

♪♪♪ I am the penguin!! Yochi-Yochi !! Hyoko-Hyoko!! Yochi-Yochi Hyoko-Hyoko--ooh!! ♪♪♪

【ぼ～くーはペンギン、よちよち、ひょっこひょっこ、よちよちひょっこひょっこーぉっ♪】

I guess there is such a song that begin singing

But I can't remember completely,and I can't find this title.

Maybe I wonder that this song is *penguin*

But We can't find out this song on website.

Is there someone who remembers this song completely?
