To catch Gimmighoul in Pokémon GO, you mainly need to use the special Coin Bag mechanic that’s tied to Pokémon Scarlet/Violet and Golden PokéStops.

How Gimmighoul Works in Pokémon GO

  • Gimmighoul in GO appears in its Roaming form, not the chest form you see in the main series games.
  • It does not spawn as a normal wild Pokémon on the map like a Pidgey or Rattata; you must trigger special spawns.
  • You evolve it into Gholdengo by collecting 999 Gimmighoul Coins and then using them to evolve your Gimmighoul.

Step-by-step: Core Method (Coin Bag)

  1. Link Pokémon GO with Scarlet/Violet
    • On your Nintendo Switch, open Scarlet or Violet, go to the Poké Portal, then to Mystery Gift, then to the option to connect with Pokémon GO.
 * In Pokémon GO, open Settings, scroll to the Nintendo Switch section, and pair with your console.
  1. Send a Postcard from GO to Scarlet/Violet
    • In Pokémon GO, open your Postcard Book (from the Items menu), pick a postcard from a PokéStop or gift, and send it to your connected game on Switch.
 * Sending a postcard unlocks the Coin Bag in Pokémon GO and also progresses you toward Golden Lure Modules.
  1. Use the Coin Bag in Pokémon GO
    • After sending a postcard, you receive or can use your Coin Bag; activating it works a bit like an Incense but only for Gimmighoul.
 * For 30 minutes, Roaming Form Gimmighoul will spawn around you roughly every 1.5 minutes on average, giving you multiple chances to catch it.

 * When the 30 minutes ends, you must wait about one day before using the Coin Bag again, then send another postcard to reactivate it.
  1. Catching tips
    • Treat Gimmighoul encounters like any other catch: use Razz Berries, Golden Razz Berries, and higher-tier Balls if you’re worried about escapes.
 * Because spawns are time-limited, it helps to walk around to maximize the number of Coin Bag spawns you see within that 30-minute window.

Extra Method: Golden PokéStops & Golden Lure Modules

  • Golden Lure Module basics:
    • By sending multiple postcards to Scarlet/Violet, you can earn Golden Lure Modules.
* When used on a normal PokéStop, a Golden Lure temporarily turns it into a Golden PokéStop.
  • What Golden PokéStops do for Gimmighoul:
    • Spinning a Golden PokéStop can yield Gimmighoul Coins and sometimes Gimmighoul encounters, depending on current event settings.
* Even when you don’t get an encounter, you still farm coins for evolution.

Evolution: Gimmighoul → Gholdengo

  • You need 999 Gimmighoul Coins to evolve Roaming Form Gimmighoul into Gholdengo.
  • Ways to earn coins:
    • Catching Gimmighoul from the Coin Bag.
* Transferring extra Gimmighoul to the Professor.

* Spinning Golden PokéStops created by Golden Lure Modules.

* Walking with Gimmighoul as your buddy can also provide extra coins over time.

Once you’ve caught at least one Roaming Form Gimmighoul via the Coin Bag and built up enough coins, you can evolve it and lock in Gholdengo for your Pokédex.
