If you're taking the "normal" path through the game (beating the gym leaders in order), the Pokéblock Case doesn't come into play until you beat Brawly and receive the Knuckle Badge. Play through the game normally up to this point.


For reference, Brawly is the Fighting-type gym leader located in Dewford City.He is the second gym leader you encounter.;
, After beating Brawly, you should receive the "Devon Goods" item from a Devon Corporation worker. You will be instructed you to take the goods to Slateport City. A convenient way to get to Slateport is to take a ride on Mr. Briney's boat (located in Dewford City, the same town as Brawly's gym).


Before Mr. Briney can give you a ride, you need to rescue his pet Wingull, Peeko. Peeko is held captive by a Team Magma grunt in Rusturf Tunnel. Defeat the grunt to rescue her., This building is to the left of the North entrance to Slateport (the one that leads to Route 110)., Once you enter the Contest Hall, you should notice this girl on your left. Simply talk to her and she will give you the Pokéblock Case — she already has two.
 Pokéblocks are made from blending berries at special locations in the game. There are two ways to do this: with the help of in-game NPCs or with the help of a friend. In Ruby, there are four spots in the game where you can blend berries with the help of NPCs:The Slateport City Contest Hall (the same building where you get the Case). There are two blending NPCs here.
The Verdanturf Town Hall. There is one blending NPC here.
The Fallarbor Town Contest Hall. There is one blending NPC here.
The Lilycove City Contest Hall. There are three blending NPCs here.
