Thwackey

The faster a Thwackey can beat out a rhythm with its two sticks, the more respect it wins from its peers.

Quick answer

How do you get Thwackey?

Thwackey can spawn in Bamboo Jungle, Jungle, Sparse Jungle, and 7 other eligible biomes (Search: On land; Sky light: Bright; Ground: Natural / Trees). It appears in tier 3 raids. Check the complete conditions below; these routes reflect AshRun's installed ATMons files.

Where to look in the wild

Choose one location below and meet its conditions together. Separate cards are alternative routes. A rarity label describes a spawn pool, not the chance of finding one on each attempt.

Before you throw a ball

Catching Thwackey

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

  1. Party order matters: the game checks the first conscious Pokémon, not the highest level anywhere in your team.
  2. With no conscious party Pokémon, this outside-battle rule allows only targets up to level 15.
  3. 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 .

Base catch-rate value: 45. This is a species value, not a percentage or a promise that a particular ball will work.
