This is a gallery of images for the episode: The Coded Map of the City Case.
Genta finds a piece of paper with weird symbols on it, and the word "Oro". The group (all except for Conan) think it could be a treasure map.
Unaware to Conan and friends there are three men searching for that piece of paper, but instead of claiming it, the men lurk and see what the kids will discover.
The group look at the first symbol on the map, it looks like the Toutoo Tower so they go to check it out.
Conan thinks the symbols on the map could relate to objects in real life, like an umbrella. The Detective Boys realise that all these symbols can be found at a clothing store.
The Detective Boys don't find any clues at any clothing stores. Conan asks if they could stop off at the book store where he finds a clue. The word "Oro" written on the map is Italian for gold. So Conan was wrong, it could be a treasure map after all!
Ayumi thinks that each of the symbols represents a sign near to the tower and if they follow the signs it should lead them straight to the treasure!
But where do they start looking? Conan thinks the Moon on the map represents Moonview Street.
Conan has an idea. The piece of paper is a map from the Tower to the Aquarium. All the symbols drawn on the map are signs that run along Moonview Street. So the only question is, what's at the end of the map?
The group has ran a long way and they still haven't seen the fifth symbol. The word Oro is Italian so an Italian must have wrote this map. Conan knows he's made a mistake and tells the group they have to go back to the beginning and start over.
Why didn't the writer just write the whole thing in Italian instead of drawing all those symbols. The Moon must have it's own meaning. Maybe the symbols are something you can only see after it's dark. Most of the symbols must represent Neon Signs!
They find all the Neon Signs but struggle to find the last one - the fish shape!
Mitsuhiko explains that although they're in a downtown area, a river runs through not too far from there. Conan realises that because all of the signs are Neon Lights the Italian Person must've seen a Neon Fish Sign, not an actual fish!
Conan explains that you can't see the fish unless your at the top of a certain building. The light reflects off the surface of the water to make it look like a fish and the eye is the light from the next building over.
Conan finds the coins are in bag attached to the ceiling.
