Pokémon Ruby and Sapphire/Pokéblocks

Pokeblocks are square candies given to Pokemon to raise their condition (smartness, cuteness, beauty, coolness, and toughness) and help a lot in contests. The first time you make Pokeblocks is in Slateport City after recieving the PokeBlock Case (see Key Items) and choose the berries needed to make the Pokeblock (see the Berry Chart for more info).
