When "Thru the Mirror" begins, Mickey has just fallen asleep after reading Lewis Carroll's "Through the Looking Glass". Then, like in the story, Mickey has a dream where he, too, is able to talk through the mirror into a strange parallel world. He finds that all the furnishings in the house are alive. Next, he eats a walnut and shrinks--and has all sorts of miniature adventures. He battles against some playing cards but my favorite portion is where he tap dances--in a manner highly reminiscent o Fred Astaire. All in all, there really isn't a lot in the way of plot but the cartoon is so much fun and the animation so nice that you really don't care! Clever and fun from start to finish.
