How Mysterious Slates Work

Finding Slates

Look for glowing yellow soil patches throughout the world. Use Rock Smash on them. You may find fossils, Lost Relics (CDs), or Mysterious Slates.

Reading the Slate

Open your inventory, select a Mysterious Slate, and press ZL to rotate it. The back of each slate has an Unown letter carved into it.

The Unown Wall

Behind the Pokemon Center in Withered Wasteland, find a cliff with light brown cracks. Rock Smash it to reveal an underground tunnel with a massive wall featuring 28 Unown letter slots.

Placing Slates

Match each slate's Unown letter to the correct slot on the wall. A chime sound confirms correct placement.

Final Reward: Mew

After placing all 28 Mysterious Slates correctly, a hidden animation plays. Mew appears from the completed mural and is automatically recorded in your Pokedex. This is the only way to encounter Mew in Pokémon Pokopia.
