Treasure maps in Pokémon Pokopia are collectibles found by digging up shining spots that spawn daily on the Bubbly Basin map for Nintendo Switch. While these maps point players toward hidden human-made valuables, you do not actually need to possess a map to find the items—you can travel directly to each location.
Quick Overview: Bubbly Basin Treasure Locations
- Treasure Map #1: Bathing house beside the Pokémon Center (Decorative Great Ball)
- Treasure Map #2: Underground room northeast of the ocean temple (Decorative Heal Ball)
- Treasure Map #3: Abandoned gym east of the main square (Decorative Dive Ball)
- Treasure Map #4: Cave northwest of the main square / Frillish location (Decorative Net Ball)
Pokémon Pokopia Treasure Map #1: Decorative Great Ball
To find the first hidden treasure, head to the bathing house beside the Pokémon Center in Bubbly Basin. Go down the stairs on the left side of the building and look for a wall of blue rocks past the bench. Destroy this wall to access a secret room containing the decorative Great Ball.
Pokémon Pokopia Treasure Map #2: Decorative Heal Ball
The second treasure is located inside an underground room northeast of the ocean temple. Swim past the tall red-roofed building to reach the area where Barboach is met during the "Build the Beautiful Building!" request. Start breaking ground blocks near the large coral to reach the room containing the decorative Heal Ball.
Pokémon Pokopia Treasure Map #3: Decorative Dive Ball
The third treasure rests near the abandoned gym in Bubbly Basin. Head east of the main square and break through the wall of dirt blocks to access the path leading to the gym. Once you reach the front of the building, turn south and destroy the wall of star-spotted rocks to uncover the room with the decorative Dive Ball.
Pokémon Pokopia Treasure Map #4: Decorative Net Ball
To collect the fourth treasure, travel to the cave northwest of the main square in Bubbly Basin—the same location where you met Frillish during the "Build the Beautiful Building!" request. Jump back into the water past the entrance to find a room blocked by nets, break them, and keep moving down. Upon reaching a room with tracks and blue crystals, destroy the wall of blue rocks on the southeastern side to enter the room holding the decorative Net Ball.
