To get shiny machoke, go to Ecrutic City and go east. In the center of that cave are level 32 Machoke, keep searching and you will find one. To get a shiny Rattata, go south of Goldenrod city and keep searching in the grass. To get a shiny pikachu go south of Pewter city and keep searching in that patch of grass. Note:It has to be dark to cach them, I repeat it has to be night time.
