* Route 31: This is the most common location to find Oddish. It appears in the tall grass.
* Route 32: Oddish can also be found in the tall grass of Route 32.

Tips for finding Oddish:
* Use a Poké Radar: The Poké Radar is a useful item for finding rare Pokémon. It can be obtained in the Game Corner of Goldenrod City.
* Use Repels: Repels can prevent wild Pokémon from appearing for a certain amount of time, allowing you to focus on finding Oddish.
* Explore at night: Some Pokémon, including Oddish, are more likely to appear at night.
* Try using a Pokémon with the Aroma Veil ability: This ability makes it more likely to encounter Pokémon that are normally rare.
Remember: The appearance of Pokémon in the wild is random, so there is no guarantee that you will find Oddish in these locations. Keep searching, and you will eventually find one!
