"Bonus Boxes" in PokéPark Wii? They Don't Exist—Here's What You Might Mean

There are no "bonus boxes" in PokéPark Wii: Pikachu's Adventure. You might be thinking of:

• Bonus Missions: Optional side quests unlocked after story milestones. Reward unique items, Pokémon, or areas.
• Hidden Items: Berries, Poké Balls, Star Pieces, and Wonder Orbs scattered throughout zones. Found by exploring, sniffing (down on D-pad), or completing challenges.
• Puzzle Blocks: Individual blocks (red, blue, yellow, green) used to unlock paths or trigger events. Not "boxes."
• Lucky Eggs: Held items that boost Pokémon's earned Experience after battles. Found in specific locations.

If you recall a specific object (color, shape, location, what it did), share more details and I'll identify it.
