The Reforma da Natureza CD-ROM had as its theme a computer brought by the Viscount to Sítio de Dona Benta. Emília uses make-believe and the computer to carry out renovations in nature. All the renovations that appear in the book appear in the game at some point: the edible book, the bird's nest, the renovation of the mocha cow, among others. The highlight is the games that Emília uses to undo the renovation.
