Phenomenon

Phenomena are a mechanic in the Generation V core series . Phenomena are a way to encounter wild Pokémon and, in some cases, items. There are four types of phenomena: rustling grass, dust clouds, flying Pokémon's shadows, and rippling water. Some can only be obtained via this method. Phenomena will only appear after the has the first Badge.
A phenomenon can be randomly triggered whenever the player takes a step in an area. Only one may be active at a time. An active phenomenon will generally continue to exist if the player moves away from it so long as they stay in the same overall location or room. A phenomenon will vanish after it is encountered or if the player picks up a visible item, encounters a wild Pokémon, interacts with an NPC, or exits the area or room entirely; it will also vanish if an NPC steps on it. Using a Repel does not prevent wild Pokémon from being encountered in a phenomenon. An active phenomenon is not saved when the game is saved.
Different phenomena are distinguished in-game by audio and visual effects; in most cases, they are named for the visual effect shown on-screen when each phenomenon occurs. The audio of a phenomenon reflects the distance between it and the player: if the player is close, the sound will be louder, and if the player is farther away (such as if the phenomenon is off-screen), the sound will be fainter but will also never stop.

Rustling grass does not occur in , but it does in .
