yes, it is for the dream world, you have to participate the international challenge and get ranked (for that, you have to play at least one battle, and you can't be dis-classified because of disconnect). After they release the ranking, you have to wait until the item appears on the Promotion Area. This way, you won 5 berries, but you can harvest then for more.

micle was released the same way. I'm waiting for Christmas and Winter cup, they released a Custap berry but the rankings still to be released.
