Rock a Billy

I would like to introduce Billy and his keeper Renoo. Billy loves nothing better than to eat rocks (hence Rock a Billy). they roam the countrside together with the other creatures of Bazoo devouring rocks. Renoo keeps all his belonging around his neck for safety.
I have a store of my handmade paper and these two pieces were the basis for this piece. A black Uni Pin pen was the inventor of Bazoo and its inhabitants. And as often happens a piece of poetry evolved as I worked. All my pieces take on a life of their own.

Over the mountains they do trek
Carrying belonging around their neck
Billy devours a feast of stones
Renoo gets tired and forever moans
The creatures laugh and tease
poor Billy and Renoo
Saying and braying
"You freaks should surely be
IN THE ZOO"
