Along the way she gets some help from a lovelorn Crow, a busybody neighbour mouse and a fearsome Great Owl. Unfortunately, Mrs. Brisby will need an engineering miracle to hoist her home, and for that she must face a mysterious rat, fend off a ferocious cat and claim a magic amulet! But when Mrs. Brisby discovers the astounding secret of NIMH...it could change her life forever!

Thumbelina: The story of a girl no bigger than a thumb who meets the king of the flower angels after escaping from an ugly toad who wanted to marry her.
