When a big tree, little tree, any kind of tree in a pot of sorts is put outdoors for fresh air, etc. and there is a fear of theft, or abuse, the tree can demonstrate tree kwon do. Tree kwon do as a form of self defense for the tree.
If a tree is put outside within a populared area, and someone tries to steal the tree, it will practice, Tree Kwon Do.
