Hmmm sounds familiar I think it is an event or has to do with Latios/Latias? Idk I'm probably wrong.

You can find the Seal Case by feeding the Miltank Oran Berries at Route 39
5 or 6.

somewhere
u place them on poke balls and when your in battle when u bring out a pokemon with a seal on their pokeballs u just see images like hearts , fire and so on
Lots of things. You can get both Hoenn and Kanto starter Pokemon (Hoenn: Torchic, Mudkip, and Treecko. Kanto: Bulbasaur, Charmander, and Squirtle.) You can also catch Groudon. If you have a bud that has HeartGold, ask them for Kyogre, and you can get Rayqaza. The final thing: talk to Blue, and he'll give you the seal case. Hope I helped!:-)
Go to the moomoo farm on route 38 and feed the sick MILKTANK oran berries till he feels better. then talk to the girls surrounding MILKTANK and you should get a seal case and some seals.
A girl in Olivine City will give some to you if you have the Seal Case, which you can get by healing the Miltank on Route 39. Heal the Miltank by giving it Oran Berries.
First, heal the farmer's Miltank with seven oran berries. The little girl will then give you the seal case. After that, you can stick seals on your ball capsules for Pokemon. *Note - Pokemon cannot be placed in the box while having a ball capsule on.
No you do not need to help the miltank it is recommended though. You need to give it 7 oran berries then you will get a Seal Case and some seals. Which can customize the way your Pokemon enters the battle.
A Seal Case, after giving it ten Oran berries.
