"No Grass, Please!" is an ambitious attempt to rectify some of the mistakes made by Blue Fang and adapt Dinosaur Digs as much as possible to present-day science. It changes many of the dinosaur stats and behaviors, including biome stats, to make your dinosaur zoo appear more plausible and, hopefully, more true to life. In addition, the mod aims to add a lot more dinosaur-themed and prehistoric-themed content to the game, from plant life to decorations, in order to create the definitive, be-all-and-end-all dinosaur zoo experience.
Woolly mammoths and rhinos share quarters with two new species: the Wisent (modified copy of American bison) and Tarpan (modified copy of Przewalski's horse).
EDIT: Wisent has been renamed to Steppe Bison. Also added Paracamelus (modified copy of Dromedary camel).
