I love how many details and hidden areas are in KH1. It's one of its strongest points in comparison to other games from the series.
Since it seems a lot of people didn't know about the bubble being freezable in Hollow Bastion, I've decided to make a list of all the secrets and details of KH 1 (That I know).
Let me know if I missed anything relevant and which ones you didn't know about ;p
