Pokemon Pokopia conceals one of its most valuable secrets behind a puzzle that rewards thorough exploration: players who track down every Mysterious Slate can unlock the mythical Mew by completing a hidden wall puzzle in the game's opening region.
What the Mysterious Slate Puzzle Is
Throughout Pokopia's world, players can discover 27 Mysterious Slates. Each slate bears a symbol on its reverse side corresponding to an Unown variant, the hieroglyph-inspired Pokémon from the franchise. Gathering all 27 and arranging them properly on a concealed puzzle wall triggers Mew's appearance, allowing players to befriend the mythical Pokémon.
The puzzle wall itself is tucked inside a secret temple that requires breaking through concealed passages near a recognizable landmark, making it simple to overlook during normal gameplay.
How to Collect All 27 Mysterious Slates
Mysterious Slates are obtained from buried treasure blocks, which emit a distinctive gold glow. These blocks spawn throughout the main map zones and on Drifloon's Dream Islands.
Key details for slate collection:
- The Dowsing Machine provides the most reliable method for locating buried treasure blocks
- The gold glow becomes more visible at nighttime, though blocks remain accessible during daylight hours
- Players appear unable to receive duplicate slates until they've obtained all 27 at least once, which eliminates much of the repetitive grind
- Creating a dedicated storage box for slates prevents them from getting lost among other collected materials
Finding the Hidden Puzzle Wall in Withered Wasteland
The secret temple containing the puzzle wall sits within Withered Wasteland, the starting area. Its entrance blends into the environment easily.
Steps to locate the temple:
- Travel to the Pokemon Center in Withered Wasteland
- Walk along the red brick pathway on the right side of the building until reaching a dirt wall
- Break through the dirt wall to access a new map section
- Instead of proceeding forward, turn left from where you broke through
- Another patch of dirt rubble appears nearby. Destroy it to reveal a stone staircase
- Descend the stairs into the underground temple
Inside, the puzzle wall displays tiles representing different Unown variants, one matching each of the 27 Mysterious Slates.
How to Solve the Puzzle and Unlock Mew
Completing the puzzle becomes simple once all 27 slates are collected.
- Drop a Mysterious Slate on the ground to examine the Unown symbol on its back
- Find the matching Unown tile on the puzzle wall and place the slate there
- Continue this process for all 27 slates until every tile is filled
Placing the final slate activates the puzzle, causing Mew to materialize. The mythical Pokémon becomes a companion that follows players throughout the world. Players will likely want to build a habitat for Mew using the Habitat Dex system.
Why This Puzzle Stands Out
The Mysterious Slate puzzle demonstrates Pokopia's commitment to rewarding exploration. Instead of locking Mew behind a simple quest or microtransaction, the game requires environmental awareness, a lengthy collection challenge, and a puzzle built around Unown, one of the franchise's most enigmatic Pokémon. Players who invest time exploring and utilizing tools like the Dowsing Machine receive a meaningful payoff.
