And to think that i saw it on mullberry street

This book is about a boy that thought up a story that no one could beat while he was walking home from school on mulberry street. His dad asked him what he had seen on his way home but he just said nothing but a plain horse and a wagon on mulberry street because he had so much to tell that he just couldn't begin. My favourite part was when he thought up a reindeer pulling a fancy sled.
