How do you catch a pikachu in Pokemon Ruby?
First you need a Acro Bike from the Mauville bike shop. Then you need a pokemon that know’s sweet scent (Tropius). Then you go to the Safari Zone and use the Acro Bike to go on the metal pole that you can not walk on or use the Mach Bike on. Then you go to the far right corner and use sweet scent in the grass. You will soon find a Pikachu or Raichu.
