As in the base game, DLC 1: Bubbly Basin for Pokémon Pokopia also features Human Records to find and collect throughout this underwater town. However, this expansion also introduces a curious new feature in the form of mysterious Treasure Maps...
In this entry of our guide, we'll show you how to obtain Bubbly Basin's Treasure Maps, the solutions and locations of their rewards so you can unlock them without any trouble, and the prizes waiting at each treasure site. There are six maps and their corresponding treasures in total.
Bubbly Basin's Treasure Maps can be found at random, buried at glowing spots that appear throughout the town. In other words, you obtain them in the same way as Lost Relics, music CDs, fossils, and other rare items.
Collecting the maps can be useful if you're accompanied by a Pokémon with the Search specialty, such as Frillish in this DLC. With the Dowsing Machine equipped, a Pokémon with this specialty can point you toward each treasure when you're reasonably close to it.
Either way, below we'll show you all six DLC maps and the solutions for finding their treasures. Finally, bear in mind that the rewards are a set of Decorative Poké Balls that are required to create the Mermaid's Gym habitat. Once you've unlocked them, their recipes may also appear among the shop's rotating daily specials.
The drawing on Bubbly Basin Treasure Map No. 1 looks like this:
To find this map's treasure, head to the cave containing the Pokémon Center building. From there, follow the path on the left until you reach some muddy water and a Hydroelectric Generator, which looks like a water wheel.
Immediately to the right of the water wheel, break through the wall to uncover a hidden room containing the reward, as shown in the image below:
The drawing on Bubbly Basin Treasure Map No. 2 looks like this:
To find this map's treasure, travel north from the town's starting plaza and use the large red pagoda-style tower protruding above the surface of the sea as your landmark. On the nearby street directly in front of this building, you should see a patch of ground partially covered in mud. Its exact position is shown in the following image:
As shown in our screenshot, you need to break through the ground here to reveal a hidden room below. Drop inside to find the reward.
The drawing on Bubbly Basin Treasure Map No. 3 looks like this:
To find this map's treasure, first head toward the entrance to the old Gym building, located slightly east of the town's main plaza. You can reach it by breaking through the rocks blocking the way. The building's entrance is easy to recognize, as shown below:
Once you're standing in front of the Gym entrance, don't go inside. Instead, look to the left, as indicated in the screenshot, and break through the stone blocks to uncover a lower cave containing the reward.
The drawing on Bubbly Basin Treasure Map No. 4 looks like this:
This map's treasure is hidden inside a deep cave filled with blue crystals in the northern part of the town—the only cave of its kind. You pass through this mine-like cave during the story while helping Female Frillish as part of the Build the Beautiful Building request, although you can visit it whenever you like.
When you reach the central section of the cave, where there are minecart tracks on the ground, smash through the wall on the eastern side, precisely where shown in the following image:
Breaking this wall will reveal a small hidden cave containing the reward.
The drawing on Bubbly Basin Treasure Map No. 5 looks like this:
To find this map's treasure, you need to enter a partially hidden basement inside a house in the northeastern corner of the town. The house is easy to identify because it has a green roof and is the only building of its kind in this part of the area:
Inside the house, you'll see several pieces of furniture and a Portal Pod. Directly behind the Portal Pod is a staircase leading down into the basement. Walk behind the machine and head down the stairs. You'll reach a small room connected to another hidden chamber containing the reward.
You can also reach this underground room directly by breaking through the ground outside, immediately to the left of the green-roofed house.
The drawing on Bubbly Basin Treasure Map No. 6 looks like this:
This map's treasure is fairly easy to find because it is close to the town's entrance gate. After descending through the passage connecting the gate to the area's main plaza, turn left. In the corner behind the ruins of a house, you'll find a group of Star-spotted Rocks.
You need to smash through these rocks—the ones located exactly where indicated in the image above—to reveal a small hidden cave containing the reward.
