... Ok, so from what I remember the movie was about a mouse, who gets tricked by this sorcerer mouse and her house sinks in the mud and is taken away from her kids and becomes a pet mouse, and then at the end she has to break the red stone that the sorcerer has... :confused:
It's a cute movie that I just can't seem to remember the title for the life of me... PLEASE HELP!! :)

Some of your details are off but the movie you're looking for is The Secret of NIMH (http://imdb.com/title/tt0084649/) (1982)
