From a quality point of view, this series of books is excellent with laminated pages and solid yet my son is far from a tender with its business. The quality is very good explanations, the designs are simple but well illustrate the text. For the specific case of "savannah animals" we are presented the African savannah during the rainy season and the dry season, and the animals that live there (zebras, antelopes, gazelles, ostriches, giraffes, cheetah, wildebeest, crocodiles, hippos, elephants). Y is explained by the gazelle hunting cheetah, hyenas and vultures attention to supporting details and pictures !!! It is very rewarding for children but attention to the smallest that can be sensitive.
