11Overview22Mysterious Slates (officially called Mysterious Slates in-game) are a set of 27 collectible stone tablets scattered throughout Pokemon Pokopia. Each slate features a carved design on the front and an Unown alphabet letter engraved on the back. Collecting all 27 slates and placing them correctly on the Mysterious Mural in the Withered Wasteland unlocks Mew, the Mythical Pokemon from Generation I. The slates are one of the most involved side quests in Pokopia and require patience, the Dowsing Machine, and a Pokemon with the Search specialty.44What Are Mysterious Slates?66When you dig up a Mysterious Slate, the game describes it as: "This mysterious stone tablet has some kind of design carved into it, and on the back are... letters?" Each slate corresponds to one of the 27 Unown forms (A through Z, plus one combined form covering both ! and ?) (A through Z, plus one combined form covering both ! and ?). The front of each slate has a fragment of a larger picture, and when all 27 are assembled on the Mysterious Mural, they form a complete image that summons Mew.88How to Find Mysterious Slates1011Mysterious Slates are found inside treasure blocks, the same glowing blocks that also contain Lost Relics, fossils, CDs, and other buried items. Treasure blocks are identifiable by the yellow glow emanating from them, indicating something is trapped inside. Break them open with Rock Smash to retrieve whatever is buried.1213Treasure Block Basics1415Treasure blocks appear in all five regions: Withered Wasteland, Bleak Beach, Rocky Ridges, Sparkling Skylands, and Palette Town.The contents of treasure blocks are randomized. You might find a Mysterious Slate, a Lost Relic, a fossil, a CD, or another item.Treasure blocks refresh every day at the daily reset time. Check back regularly to find new ones.You will never find a duplicate Mysterious Slate until you have collected all 27 unique slates. This guarantees steady progress toward completing the set.1617Using the Dowsing Machine1819While some treasure blocks are visible on the surface as glowing dirt or grass patches, many are buried deeper underground and invisible to the naked eye. The Dowsing Machine is essential for locating these hidden deposits.2021How to get the Dowsing Machine: After learning Rock Smash from Hitmonchan in the Withered Wasteland, Hitmonchan eventually asks you to climb a hill to the west of the Pokemon Center. At the top, you will find a yellow Poke Ball under some breakable rocks. Break the rocks with Rock Smash to collect the Dowsing Machine.2223How to use it: Equip the Dowsing Machine and make sure a Pokemon with the Search specialty is following you (Pidgey, Venonat, Drilbur, or any other Search-specialty Pokemon). Press and hold A to activate the machine. You will hear a beeping noise that gets faster as you approach a buried item. Your companion Pokemon provides directional hints such as "below here" or "above here." Once you locate the block, use Rock Smash to break it open.2425Good early Search-specialty Pokemon include:2627PokemonRegionNotesPidgeyWithered WastelandAvailable early; also has Fly specialtyVenonatWithered WastelandEasy to attract with basic habitatsDrilburWithered WastelandFound underground; also has ChopParasWithered WastelandAnother early Search option2829The Mysterious Mural2930The Mysterious Mural is located in a hidden underground room in the Withered Wasteland. To find it:3132Start at the Withered Wasteland Pokemon Center.Head north through the tunnel leading away from the center.Look for a destructible wall on the left side of the tunnel. Break through it with Rock Smash.Go down the stairs to discover the cellar room containing the Mysterious Mural.3335The mural wall displays the entire Unown alphabet with 27 indentations, one for each of the 26 letter forms plus one combined form covering both ! and ?. Each indentation is shaped to accept a specific Mysterious Slate.3537Placing Slates Correctly3739Each Mysterious Slate must be matched to its corresponding Unown symbol on the mural wall. To figure out which slot a slate belongs in:3941Open your inventory and select the Mysterious Slate you want to place.Check the back of the slate to see which Unown letter is engraved on it.Find the matching Unown symbol on the mural wall.Stand in front of the correct indentation and place the slate.Use ZL to fine-tune the positioning. Orient the slate so the letters face the wall and the protruding carved design points outward.Standing on nearby blocks can help with placement for higher slots on the wall.4143When a slate is placed correctly, you will hear a confirmation jingle and see a sparkle effect. Incorrectly placed slates will not lock in, so there is no risk of putting one in the wrong spot permanently.4345Completing the Mural: Unlocking Mew4547Once all 27 Mysterious Slates are placed on the mural, the fragments combine to form a complete picture. This triggers a special event where Mew, the Mythical Pokemon, appears in the mural room.4749After the encounter, Mew stays on your island permanently. You can:4951Build Mew a home by creating a suitable habitatAsk Mew to follow you around your islandUse Mew's Teleport specialty to fast-travel to any befriended Pokemon across your islands5153Mew is Pokopia Pokedex entry #300 and is the only Mythical Pokemon in the game. Its Teleport specialty is shared with Pokemon like Abra, Kadabra, Alakazam, Ralts, Kirlia, and Gardevoir, but as the final Pokedex entry, collecting Mew represents full completion of the slate quest line.5355Tips for Finding All 27 Slates5557Search daily. Treasure blocks refresh every day. Make a habit of scanning each region with the Dowsing Machine as part of your daily routine.Cover all five regions. Slates can appear in any region, so do not limit your search to just the Withered Wasteland. Bleak Beach, Rocky Ridges, and the other areas all have their own treasure block spawns.Upgrade your Search Pokemon. Stronger Search Pokemon like Excadrill or Crobat may locate buried items more efficiently than smaller Pokemon.Check Dream Islands. Dream Island treasure blocks also refresh and can contain Mysterious Slates, providing additional chances per day.No duplicates until complete. The game guarantees you will not dig up a duplicate slate until all 27 unique ones are found. Every slate you find brings you one step closer.Track your progress on the mural. Visit the mural room periodically to see which Unown letters still have empty indentations. This tells you exactly how many slates remain.Powered-up Rock Smash. Some treasure blocks in deeper areas of Rocky Ridges require powered-up Rock Smash (eat a Hamburger Steak) to break. Do not skip these blocks, as they could contain slates.5759Related Collectibles5961Mysterious Slates share the treasure block system with several other collectible types:6163CollectibleDescriptionLost RelicsFurniture items found in treasure blocks; appraise them at Professor Tangrowth to identify and place themFossilsFossil fragments displayed on Exhibition Stands to attract fossil PokemonCDsMusic tracks for DJ Rotom's Stereo Form; play background music on your islandAncient ArtifactsRare decorative items with historical significance6366All of these items are found through the same treasure block and Dowsing Machine mechanics, so searching for slates naturally yields other collectibles as a bonus.
