The second one is alright but the third one seems to ignore it completely in terms on the canon. Each of the sequels is basically standalone, except in relation to the first film of course. The second is a bit like the "TV show sequels" that Tarzan and Atlantis got. I'm not sure it was the intention, but it basically tells three short stories and the reasoning is that the mice are making up a new book because continuously reading Cinderella over and over gets old.
