Learn how to S.O.S. chain Ditto infinitely in Pokémon Ultra Sun and Ultra Moon by using a Munchlax with Recycle and a Hypno with Switcheroo and a Leppa Berry.

Walkthrough
  1. 1
    Preparation:
    • Catch or breed a Munchlax. Take it to the Move Tutor in Mount Lanakila’s Pokémon Center to relearn Recycle.
  2. 2
    Go to the Move Deleter in Hau’oli City’s Pokémon Center and delete all of Munchlax's other three moves, leaving only Recycle.
  3. 3
    Catch a Hypno from Poni Plains. Use the Move Reminder to teach it Switcheroo if it doesn't know it.
  4. 4
    Have Hypno hold a Leppa Berry. These can be found from Berry Trees or cultivated in Poké Pelago.
  5. 5
    Ensure you have plenty of Poké Balls, especially Timer Balls for long chains.
  6. 6
    Bring a powerful Pokémon with False Swipe (e.g., Decidueye, Garchomp) to lower the target Ditto's HP to 1.
  7. 7
    Battle Setup:
    • Find a Ditto in the grass at Mount Hokulani.
  8. 8
    Switch your lead Pokémon to your prepared Munchlax. Ditto will transform into Munchlax.
  9. 9
    Immediately switch to your Hypno holding the Leppa Berry.
  10. 10
    Use Switcheroo to give the Leppa Berry to Ditto. Ditto will now only know Recycle and hold a Leppa Berry, granting infinite PP for Recycle.
  11. 11
    Use an Adrenaline Orb to increase the chance of wild Pokémon calling for help.
  12. 12
    Use False Swipe on the base Ditto to bring its HP down to 1, maximizing the chance of allies being called.
  13. 13
    Continue to S.O.S. chain until you are satisfied, being careful not to defeat the base Ditto, which is essential for the infinite PP setup.
Tips
  • Timer Balls are recommended for long S.O.S. chains.
  • Ensure the base Ditto is at 1 HP to maximize ally calls.
  • Do not defeat the Ditto that has the Leppa Berry, as it is the source of the infinite PP.
