Barry Big Oak is about a young boy who bumped into a talking oak tree while wandering in a wooded area on his father's farm. Barry Big Oak spoke "Tree Language" which had a lot of "S" sounds that represented the wind. After Big Barry taught Sammy how to speak "Tree Language" Sammy entered into an adventure with him to resist the "Cloud Forces" who were set on destroying Big Barry and his "Tree Forces" by using dry weather lightning to set the forest on fire.
