* Collecting Tokens: Certain Pokemon can be unlocked by collecting specific tokens scattered across the game's levels.
* Unlocking areas: Some areas might be unlocked by completing certain tasks or challenges within the game.
Where passwords are used in other Pokemon games:
* Pokemon Mystery Dungeon: Some games in this series use passwords to unlock bonus items, characters, or features.
