Before you throw a ball

Catching Iron Boulder

If you encounter a wild Iron Boulder, catch it in battle after unlocking its matching regional Pika Star advancement.

Follow the acquisition route on this page first; a special label does not mean it spawns naturally.
Check the required region in the battle message. Regional forms can need a different star from the original species.
Use a ball during the battle. Even a Master Ball cannot bypass the outside-battle restriction.

These rules describe wild encounters. Raids and scripted encounters may use their own capture flow. Read the catching guide and blocked-throw checklist · Checked 2026-10-16.

Base catch-rate value: 10. This is a species value, not a percentage or a promise that a particular ball will work.
