Woody and Pencil are parts of trees, but Tree is the real thing. He is a tree with leaves, although he seems to be evergreen. It doesn't matter. Tree is not anchored by roots, but he thinks of himself as a with-it-down-to-earth type of guy; only Loser's charming charisma can sweep him on his feet. When he sees a problem, Tree knows what not to do, although he hasn't a clue on what he should do. When Tree is fed up, he'll walk away and tell people that he is "leafing".
