The key is atmosphere

Exploration Stage: Airship Dock
From: Detective
Description: I would love a romantic place for a date with Juliette. Too bad there aren't many places like that in town. But we can create a nice atmosphere. How about finding a painting of Paris?
Completed: It's an enchanting Parisian painting. You have good taste, buddy. If you put it on the window sill, it will look like a real landscape. I wonder if Juliette will like it.
