Tips

• Both Nidoran forms are common in the grass, plus Mankey, Spearow and Rattata.
• The first rival battle is optional and disappears after you win the Boulder Badge.
• In Yellow, how the first fight goes affects which Pokémon his team has later on.
• The Super Rod can pull up Poliwag and Poliwhirl from the pond.
• Heal fully before the later rival battle, because it is tough.
