Wondering how to evolve Gimmighoul in Pokémon GO? Find out why your 10th-anniversary event variant won’t transform and exactly how to farm your 999 coins.
You have been walking for miles, spinning every stop in sight, and you finally hit that magic number. You open your Pokémon storage, ready to figure out how to evolve Gimmighoul in Pokémon GO, but your heart sinks. The evolve button is completely missing.

If you are frantically tapping your screen right now trying to figure out what went wrong, take a deep breath. Your app isn’t broken, and you aren’t missing a hidden trick.
Here is exactly what is happening with the latest event, why your new catch won’t transform, and how you can actually add a Gholdengo to your Pokédex.
Why Can’t I Evolve Gimmighoul in Pokémon GO?
If you recently caught this little coin-chest creature during the 10th Anniversary Party event, you probably noticed it has a shiny new 10th-anniversary coin strapped to its back. While it looks awesome in your storage—especially if you snagged the rare shiny variant—it comes with a frustrating limitation.
Niantic treats this specific anniversary version as an event variant. It falls under the exact same costumed Pokémon restrictions as a Pikachu wearing a winter beanie or a Spheal wearing a scarf.
So, if you are looking to evolve 10th anniversary Gimmighoul, you are out of luck. This particular version is permanently locked as a base form collectible. It simply cannot evolve, regardless of how many coins you have stockpiled in your bag.
How to Get Gholdengo in Pokémon GO (The Standard Method)
Now that we have cleared up the anniversary event confusion, you are probably wondering what to do with all those Gimmighoul 999 coins you just spent weeks collecting.
To actually get a Gholdengo, you need to use your hard-earned coins on a standard Roaming Form Gimmighoul. This is the regular, non-costumed version originally discovered in the Paldea region.
If you don’t have one in your storage yet, here is a quick guide on how to get Gholdengo Pokémon GO style, using the official Pokémon Scarlet and Violet connection.
Step 1: Connecting Your Devices
To trigger the standard version to spawn, you need to link your mobile phone to a Nintendo Switch console.
- Boot up your Nintendo Switch and launch your copy of Pokémon Scarlet or Pokémon Violet.
- Open the Poké Portal in the Switch game, select the Mystery Gift option, and choose to connect to Pokémon GO.
- Launch Pokémon GO on your phone, head into your Settings, tap on Connected Devices and Services, and pair it with your Switch via Bluetooth. (Note: Bluetooth pairing between phones and consoles can sometimes be finicky, so keep both devices close together and ensure your phone’s Bluetooth is turned on).
- Send a postcard directly from your Pokémon GO item bag over to your Nintendo Switch game.
Step 2: Unlocking the Pokémon GO Coin Bag
Once you successfully transfer a postcard to your console, you will be rewarded with the Pokémon GO Coin Bag.
You can think of this special item as a highly targeted incense. The moment you activate it, standard Roaming Form Gimmighouls will begin popping up around you for exactly 30 minutes. Make sure you have plenty of Poké Balls ready!
Step 3: Farming 999 Coins Fast
If you haven’t quite reached the 999 coin threshold, you will need to keep grinding. You pick up coins naturally by catching Gimmighoul, walking with one set as your active buddy, or spinning PokéStops.
Pro Tip: Want to speed things up? Work toward getting a Gimmighoul Golden Lure Module. You get one after sending five postcards to your Switch across five different days. When you drop this module on a PokéStop, it turns the stop gold and massively boosts the coin drop rate. If you want to maximize your haul, open up the Niantic Campfire app or hop into your local community Discord server to organize a “lure party” where everyone drops their Golden Lures in one park!
