The presence of a Pokémon constantly following the player inherently called for a restoration of all main game events, in all areas.

However, this mechanic may be disabled in special locations (the Underground) or circumstances (riding the bike). Your Pokémon’s reactions may vary depending on how strong your bond is and where you currently are, and the classic HeartGold and SoulSilver emoticons will pop up depending on your Pokémon’s mood. The Walking Pokémon feature allows you to walk around with your favourite Pokémon throughout the entire game and interact with it whenever you want, as in Pokémon HeartGold and SoulSilver.
