Why slip out of the box when you can wear it on your body like a piece of clothing? Tom Maru obviously has this idea too and at the beginning of the film shows once again how skillfully he can slip into packaging. He crawls in from the floor, or sticks his head in the box: the velvet paw is not unimaginative when it comes to maneuvering into a box.
Then Maru apparently no longer wants to brush his favorite toy off the fur again and again and he carries the piece of cardboard around a bit in the apartment. Even his animal roommate, cat Hana, is very fascinated and looks after her buddy with suspense - Maru knows how to impress.
