Shroomish

If Shroomish senses danger, it shakes its body and scatters spores from the top of its head. This Pokémon's spores are so toxic, they make trees and weeds wilt.

Before you throw a ball

Catching Shroomish

If you encounter a wild Shroomish, an ordinary throw outside battle requires your first non-fainted party Pokémon to be at least its level.

Party order matters: the game checks the first conscious Pokémon, not the highest level anywhere in your team.
With no conscious party Pokémon, this outside-battle rule allows only targets up to level 15.
A guaranteed-catch ball bypasses this ordinary level check. You can also battle a wild target and use a ball during your turn.

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: 255. This is a species value, not a percentage or a promise that a particular ball will work.
