Location of the Unown mural puzzle in Pokopia
The puzzle needed to unlock Mew is hidden inside the Withered Wasteland, one of the more mysterious regions in Pokémon Pokopia.

Near the local Pokémon Center, you will find a breakable wall positioned on the left side of the building. Breaking this wall reveals a secret chamber that contains the Unown Mural, a stone wall filled with empty slots designed to hold Mysterious Slates. This mural functions as a puzzle board, and each slot corresponds to one of the 27 slates you must collect.
The mural itself resembles a collection of Unown-style symbols, hinting at the ancient connection between the mysterious Pokémon and the puzzle that summons Mew.
How Mysterious Slates work in Pokémon Pokopia
Mysterious Slates are collectible puzzle items scattered throughout the world. These items do not appear in fixed locations and instead drop randomly from shiny sparkles found on the ground while exploring different areas.
It is important to note that these shiny spots must appear on land. Slates will not spawn from shiny spots found in water, which means your farming efforts should focus on exploring terrestrial areas.

Because the drops are random, obtaining all 27 slates requires patience and consistent exploration. As you travel across regions and interact with ground sparkles, you will gradually accumulate the pieces needed to complete the mural puzzle.
How to unlock Mew in Pokémon Pokopia
Step 1
Begin by exploring the world and collecting Mysterious Slates from shiny spots that appear on the ground. These glowing sparkles can appear in multiple areas, and interacting with them gives you a chance to receive a slate.

Step 2
Continue gathering slates until you have all 27 Mysterious Slates in your inventory. Since the drops are random, this step may take some time depending on how frequently the sparkles spawn during your exploration.

Step 3
Travel to the Withered Wasteland and locate the Pokémon Center in that region. Once you arrive, move toward the left side of the building, where you will find a destructible wall.

Step 4
Break the wall to reveal a hidden chamber containing the Unown Mural puzzle. The mural has multiple slots where the collected slates must be inserted.

Step 5
Open your inventory and begin placing the Mysterious Slates into the mural. Holding the X button automatically organizes the slates inside your bag, making it easier to manage them while inserting each piece.

Step 6
As you place each slate, watch for a sparkle effect on the mural slot. This sparkle confirms that the slate has been inserted correctly.

Step 7
Repeat the process until all 27 slates are placed in their proper slots on the mural.

Step 8
Once the mural puzzle is fully completed, a glowing portal will appear directly in front of the Unown mural.

Step 9
Interact with the portal to trigger the event that registers Mew in your Pokédex, successfully unlocking the mythical Pokémon.

Mew thrives best in a warm habitat environment, meaning players who manage habitats or environmental systems in Pokémon Pokopia should ensure the climate conditions are warm if they want Mew to remain comfortable.
Warm habitats generally include areas with bright lighting, open play spaces, and decorative elements that encourage exploration. Because Mew enjoys play spaces, strange objects, and sweet flavors, designing habitats with these elements can help maximize interaction with the Pokémon.
Why the Mew puzzle is one of Pokopia’s biggest secrets
The method for unlocking Mew reflects the traditional mystery surrounding the Pokémon throughout the franchise. Rather than appearing through a simple encounter, the game requires players to explore, collect hidden items, and solve an ancient puzzle tied to Unown lore.
The requirement of collecting 27 slates also encourages players to thoroughly explore the game world, ensuring they interact with many areas that might otherwise be overlooked.
