The Mouse and His Child by Russell Hoban is a fascinating epic about a toy mouse and His Child that start off dancing in circles, but wind up getting into one adventure after another, some rather ghastly. I bought this at a sale of a personal library of a children's book scholar and it had all kinds of stickie notes in it, noting symbolism and themes throughout. I loved the weirdness of some of the characters like the scientific Muskrat, who says Why times How equals What. I'd never heard of Hoban before, but now I'd like to read more.
