Completing the Medallium in Yo-kai Watch 2 is a nightmare. Honestly, there is no other way to put it. You’ve got three different versions of the same game—Bony Spirits, Fleshy Souls, and Psychic Specters—and they all gatekeep specific monsters like they're guarding the crown jewels. If you are trying to collect every yo kai watch 2 yokai for one save file, you’ve likely realized that the game is actively working against you. It isn't just about luck; it's about the fact that certain spirits literally do not exist in your game's code depending on which box you bought.
It’s frustrating. You spend eighty hours befriending rare S-ranks, only to realize you can’t get Slimamander because you picked Fleshy Souls instead of Bony Spirits. Or maybe you're staring at an empty slot where Tyrat should be, but you can’t get him because you didn't link your game with a friend's copy.
The struggle is real.
But here is the thing: it is possible. You can get those missing entries. You just have to be smart about how you use the trade system, the StreetPass features, and the specific "Link" bonuses that Level-5 baked into the experience.
The Version Exclusive Wall
The biggest hurdle for any collector is the version-exclusive list. In Bony Spirits, you get Venoct. In Fleshy Souls, you get Kyubi. If you’re playing Psychic Specters, you get a bunch of "Wicked" Yo-kai and Darknyan, but you lose out on the specific quests for the original mascots unless you’ve transferred data.
It's a mess.
If you want yo kai watch 2 yokai for one save file, you are going to have to trade. There is no "glitch" or "secret code" that spawns a Fleshy Souls exclusive in a Bony Spirits save file. You need to find a community. Whether it’s the dedicated subreddits or Discord servers that are still active years later, trading is the only path for exclusives like Watchi-gotchi or the Gemnyans.
The Gemnyans are particularly annoying. Sapphirenyan, Emeraldnyan, Rubynyan, Topaznyan, and Dianyan were originally tied to physical QR codes from the collectible medals. While you can still find those codes online today, getting all of them onto a single save file requires a lot of back-and-forth scanning and specific map hunting.
Those Pesky Rare Spawns
Then there are the "Rare" variants. We aren’t even talking about version exclusives anymore; we’re talking about standard Yo-kai that just refuse to show up.
Take Agon, for example. Or Chilhuahua. These require specific fusion items that only drop from the Crank-a-kai or high-level Terror Time chests. If you’re playing on one save file, your daily Crank-a-kai pulls are your lifeblood. You get a random number of pulls every day—anywhere from 3 to 10—and once they’re gone, they’re gone. You can't just reset your game to get different results. The "seed" for your Crank-a-kai is determined the moment you start your save file.
Basically? Your destiny was written before you even met Whisper.
The Mystery Way and Linking Games
If you want the "God-tier" exclusives like Shiny Venoct or Jetnyan, you have to use the "Link" feature. This is where most solo players hit a dead end. To unlock the Mystery Way—a special dungeon area—you have to link a Bony Spirits save with a Fleshy Souls save.
If you have Psychic Specters, you can link with both to unlock the "Gold" version of the dungeon.
For a player trying to get all yo kai watch 2 yokai for one save file, this usually means owning two 3DS systems or having a very patient friend. When you link the games, you get a "Link Key." This key opens paths in the abandoned San Fantastico station that lead to bosses you cannot fight anywhere else. These bosses, like Gargaros or Orcanos, have a chance to befriend you.
Without linking, those Medallium slots will stay gray forever. It’s a harsh reality of 2010s-era monster collection games. They wanted you to buy every version. They wanted your friends to buy every version.
Why Psychic Specters is the Best Base
If you are starting fresh and want the best chance at a full Medallium, you have to start with Psychic Specters.
Why? Because it’s the "definitive" version. It allows you to befriend the Wicked Yo-kai, which were previously un-befriendable bosses in the first two versions. It also gives you access to the Gera Gera Resort. This area is packed with high-level spirits and exclusive quests for characters like Darknyan and the specialized "Illuminoct" and "Darkyubi."
However, even in Psychic Specters, you can’t get everything. You still have to choose between the Bony or Fleshy factions during the main story. Your choice dictates which high-end questline you get. If you choose Bony, you get the Venoct quest. If you choose Fleshy, you get the Kyubi quest.
Choose carefully. You're stuck with it.
The Legendary Grind
Legendary Yo-kai are the ultimate goal. To summon someone like Elder Bloom or Gilgaros, you need a specific set of eight Yo-kai.
This is where the yo kai watch 2 yokai for one save file challenge becomes a logistical puzzle. For Elder Bloom, you need:
- Statiking (A notorious rare spawn from the Infinite Inferno)
- Peppillon (Only found at the top of Mt. Middleton in specific weather)
- Rhinormous
- Betterfly
- Mokke
- Ol' Saint Trick
- Pookivil
- Bloominoko
Some of these are easy. Some, like Statiking, will make you want to throw your 3DS across the room. He only appears on the 1st and 2nd circles of the Infinite Inferno, and his spawn rate is abysmal. You’ll spend hours running in and out of rooms just to see his sprite.
And then? You have to actually befriend him. Give him "Amazing Milk." Hope the heart bubbles appear. Use a Poke. It’s all a game of percentages.
Actionable Steps for Your Save File
If you are serious about completing this, you need a plan. You can’t just wing it and hope for the best.
First, exploit the Crank-a-kai. Don't just throw random coins in. Save your Special Coins and Five-Star Coins for when you have a high number of daily pulls. Use the "Crank-a-kai" trick by checking your results, and if they're bad, use those pulls on different colored coins to "cycle" the RNG seed.
Second, maximize your StreetPass. If you have a second 3DS, set up a dummy save file on a different version and StreetPass yourself. This is the most reliable way to get Pandanoko. Pandanoko is the rarest Yo-kai in the game because he only appears in the Wayfarer Manor after a StreetPass hit, and even then, the spawn rate is tiny.
Third, focus on the "Daily Be-friendables." There are several Yo-kai you can only fight once a day. This includes the Fruitnyans (if you have the QR codes), the Oni (if you're brave enough for Terror Time), and Master Nyada. Make these a part of your morning routine.
Fourth, don't sleep on the Infinite Tunnel. Located in Harrisville, this tunnel grows longer every day you enter it. Once you get past 10,000 yards, the Yo-kai that appear are incredibly rare. It’s one of the few places where you can find S-ranks just wandering around in the wild.
Final Strategy Checklist
- Secure the Version Transfers: If you started on Bony or Fleshy, transfer your save to Psychic Specters immediately to unlock the endgame content.
- Target the "Gatekeeper" Legendaries: Focus on befriending Statiking, Swelterrier, and Peppillon first, as these are the hardest requirements for the Legendary seals.
- Use the Camera: Don't forget the Yo-kai Cam on the start menu. Taking pictures of specific things can grant you items that make befriending easier.
- Join a Legacy Community: Since the official Nintendo servers have changed over time, look for fan-run trade hubs to swap your version-exclusives for the ones you’re missing.
Completing the Medallium on a single save file is a marathon, not a sprint. It requires patience, a bit of social networking for trades, and a massive amount of "Amazing Milk." Keep pushing through the Infinite Tunnel and eventually, that 100% completion mark will be yours.
