in pokeballs on the ground.
Dude. Just use pickup ability. Seriously.
use cheats or find 100 rare candys yourself or do 100 trades with a friend with a Pokemon holding a rare candy
Yes you can use Pickup in Platinum. The only Pokemon that may have this ability are: Meowth, Phanpy, Aipom, Munchlax, Teddiursa, Zigzagoon, Linoon, Pachirisu and Ambipom. You can pick up as much Rare Candies as you want. Pokemon that are under lv21 have no chance of finding a Rare Candy. Higher lvl Pokemon have more chances of finding Rare Candies.
how could you find 31 rare candys
There's always the lottery and the Easter egg.
you usually just find them in the items you find on the ground
