I sing this song at camp, and my song leader ends with this verse:

One bright shiny morning, as Puff walked down the strand,
a little girl came up to him and said, "Here, take my hand.
Hey, now Mr. Dragon, don't you look so sad.
My name is Jenny Paper. I was sent here by my dad."

My song leader says he saw Peter, Paul, and Mary sing this verse in a concert, but people got angry, saying it contracted from the meaning, so they didn't do it anymore.
