Puff (The Magic Dragon)

Many people love this song but feel dissatisfied by how it ends. We have seen many suggested new final verses. Here is one:

Jackie heard him crying and came to his rescue
Oh Puff, he cried, I'm feeling sad that I did this to you
I'm a grown up person but I still like to play
I'm coming back and bringing friends I've met along the way!

 Does anyone know who wrote this?
