The merchandise turns out to be extremely popular; Greninja himself gets a small popularity boost in japan and wins the biggest poll. Gamefreak sees they can capitalize on this and throw the respective audience a bone in the form of a non-canon Greninjash appearance.
That's all there is to it. Just a little Cameo for fags that watch the anime.
