In KH 1, after playing the world's canon plot we could revisit them and, sometimes, there were optional bosses (Agrabah one, Neverland one and Sephiroth). What I want to know is what do we get if we revisit all the worlds in BbS.. Dunno, maybe a secret non-canon boss? (I'm not talking about Vanitas' Sentiment)
That's it.
That's it.
