Treasure Maps

In the Bubbly Basin, alongside the Lost Relics and CDs that are found in hidden spots each day, you will also find the 6 Treasure Maps. These maps give a basic design of Cerulean City how it was and shows where treasure was placed.

With this, you can take a Pokémon with the Search Specialty and the Dowsing Machine and can go and find each of the items. These items are all required for the final habitat, Mermaid's Gym

After you have first obtained them, you will them be able to get recipes to create them in the daily shop specials.

Treasure Map #1 will lead you towards the Decorative Great Ball. This can be found behind the building to the west of the Pokémon Center. When you go around near the water wheel, you can knock out the wall to the east to find the room which has the Great Ball.

Treasure Map #2 will lead you towards the Decorative Heal Ball. This is located to the east of the main area. In the area, you will find a pagoda with a windmill on top that breaks through the waterline. This is the key point of interest. If you go along the path towards the west, you will be able to break downwards to find the room with the Heal Ball

Treasure Map #3 will lead you towards the Decorative Dive Ball. This is located next to the main area alongside Cerulean City's former gym. Next to the gym are a lot of Star-spotted rocks. If you break through them, you will find the entrance which leads you to the room with the Dive Ball

Treasure Map #4 will lead you towards the Decorative Net Ball. This is located in the cave you first found Frillish in during the game's story towards the north of the area. Follow the cave through to the mines and go east of where the giant crystal is. Break through the rock and you will find a room with the Net

Treasure Map #5 will lead you towards the Decorative Lure Ball. This is located in the north of the area near Bill's House, the only house with a green roof. If you go west and go to the sole Talll Grass next to the cliffs and dig down, you will find the room which contains the Lure Ball

Treasure Map #5 will lead you towards the Decorative QuickBall. This is located in the main area just north of the Gate that brought you into the area. If you go left, alongside the ruins of a building you'll find a wall with Star-spotted rocks. Smash the rocks and you'll find a path to the room with the Quick Ball
