Right from the wiki's page on the Dream World. The part in bold is what caught my interest. Where is this 'game' that lets us obtain an Eevee? It can't just be said like that, it needs more detail. What is this game? Where is it? Where is it available? I would like to know these things, especially with the delayed launch of the USA Dream World.
The English version of Dream World was intended to be available starting March 30, but the Tōhoku earthquake delayed the launch. A game that allows players to obtain one of the Eeveelutions with different abilities has though been made available March 28.
