A large wooden box, seemingly quite strong, but nevertheless it is rewound with chains and locked with a padlock.  For what?  Everything is simple.  Locked inside is a hellspawn dangerous to the world.  But still, Pocket Herbert, the hellspawn in this box, is quite friendly and nice to some mortals and immortals...but don't disappoint or anger him, it might end badly.  Release him!  Open the box!  He is tall, handsome and gentle.. A real gentleman.. Though he talks a lot..
