The Pester Ball is unlocked after achieving a certain score in the Beach course. These throwable items are used to provoke Pokémon, knock them out of trees, or reveal hidden areas.
- Provoking Reactions: Hitting a Pokémon with a Pester Ball can make it angry, cause it to attack, or perform a unique animation.
- Knocking Down: Use Pester Balls to dislodge Pokémon from high places, like the Mankey in the Beach course.
- Revealing Secrets: Crucially, Pester Balls can be used to break objects (like the Moltres egg or ice blocks) or reveal hidden Pokémon (like Porygon).
Pester Balls are essential for uncovering many of the game's secrets and getting unique action shots. They are a powerful tool for interaction.
