Another instance is a daily change. After completing Zone 3, you will unlock the Safari Jungle. This Zone will unlock. As you progress through the game, after Zone 6 you will unlock the second stage and completion of the game unlocks the final stage. The stages increase in difficulty with Stage 1 being relatively easy, and Stage 3 sending multiple powerful Pokémon at you.
The Pokémon that you will find change on the passing of each day. Each of the seven days of the week has got a specific roster of Pokémon for capture, requiring you to be sure to play each day in order to fill your Pokédex. The Safari Jungle runs just like the other stages and has hidden Pokémon that require high combos to access.
