Go to a cave called Ravaged Path and explore (the player can’t get through the cave without Rock Smash HM in their Pokétch, but it’s still good to go to the area)
Catch some Pokémon (optional:
Budew (grass)
Bidoof (grass)
Kriketot (only morning and night)
Shinx (grass)
Starly (grass)
Zubat (only night)
Find the Paralyze Heal to the right behind the fence, in the long grass
Challenge some trainers and opponents:
Lass Samantha with Budew (Level 7)
Lass Sarah with Bidoof (Level 7)
Youngster Tyler with Magikarp (Level 5) and Starly (Level 5)
Go into Ravaged Path, and the player can catch Psyduck and Geodude
