Cool! Uh, honestly, Marco lives in De Chima but can be found almost anywhere. He's an explorer, and the fact that he can fly after Porting means traveling is pretty easy for him.

Is it terrible I want to suggest Mexican supermarket as Marco is trying to find food (because Eva did still cook when he was a kid plus he's a CA kid so he has standards for his Mexican and this America's Porter cities are not cutting it sorry.)
