It's dubbed!

Once upon a time, a little doggy poo lived on the side of a road. He felt all alone in this world. He believed that nobody needed him for anything, and that he had no purpose in life. If only Doggy Poo had a reason for being, then he wouldn't give up on his dream to be useful to this world. One day, Doggy Poo meets a lovely dandelion sprout. Will she explain his purpose in life? Will she help him make his dream come true?
