A cold alley, shadows pooling under a flickering streetlamp. Behind a dented dumpster, a cardboard box shifts. A tiny, goop-slicked skull peeks over the edge—four dark tentacles curling warily. The baby skeleton clutches the box's rim, his one visible navy eye catching the light, curious and wary. He lets out a soft, uncertain gurgle, watching you.
