Shaymin is not directly catchable in Pokémon Scarlet or Violet in the wild. It is typically obtained through special events or distributions. Here are the detailed steps to get Shaymin:

### Step-by-Step Instructions to Obtain Shaymin in Pokémon Scarlet and Violet

1. **Check for Events and Distributions:**
– Keep an eye on official Pokémon news and updates for any event announcements where Shaymin might be distributed as a special gift.
– Ensure you are signed up for the Pokémon Trainer Club newsletter to receive notifications about upcoming events.

2. **Transfer from Older Games:**
– If you have save data for Pokémon Sword or Shield, you can transfer Shaymin from Legends: Arceus to Pokémon Scarlet and Violet.
– You can also transfer Shaymin from Brilliant Diamond and Shining Pearl, but this method involves obtaining the Oak’s Letter, which allows access to Flower Paradise where Shaymin can be captured.

3. **Shiny Shaymin:**
– If you have access to Brilliant Diamond and Shining Pearl, you can use the Oak’s Letter to capture Shaymin. Since Shaymin is not affected by the Shiny Charm, you will need to soft reset the game multiple times to increase the chances of encountering a shiny version.

4. **Sky Form Shaymin:**
– To change Shaymin’s form to Sky Form, you need the Gracidea Flower. This item can be obtained in the Porto Marinada Auctions if you have Shaymin in your party or in one of your boxes.
