Everyone knows that trees are alive…but today we are only concerned with the ones that run around.  We are talking treants from D&D, Ents from Lord of the Rings, and the Fighting Trees of Oz.  Are these creatures plants with animal traits, or secret animals that look like plants?  We discuss the possibilities.  The answer may be found in upside-down jelly fish & leafy sea slugs.  Plus we show you the importance of poemifying your life, and indulging in a little tree sap.
