Though Square’s showing of Kingdom Hearts III was, for the most part, nothing new, the brief trailer did reveal that, along with Frozen, Ratatouille will be making an appearance in the game.

The trailer doesn’t seem to clarify whether Sora enters the film’s world itself or whether Remy the rat just makes an appearance as a non-playable character, but it’s wonderful that Square are including more from the back catalogue, especially these wildly underrated films like Ratatouille.
Kingdom Hearts III, as announced a few days ago, will release January 29, 2019.
