Maru lies in the box. A master of relaxation, he possesses a Zen-like ability to slow his bodily functions so that he achieves pure stillness. Except his tail, which does most of the thinking. Maru’s tail cannot fit into the box. This is untidy and vexes Maru’s tail. There can be only one solution: A smaller box.
