There’s no messy fiddling with menus, either. Various icons tell you what each animal is thinking, so you’ll know whether they’re hungry, tired or ill. If you have more than one of a particular type of animal, you’ll be able to recognise them from slight adjustments to their appearance. One might have a white stripe on its tail, another you’ll think about naming ‘Patch’ after the distinctive marking on their ear. It’s about flora as well as fauna too. Rare plants can make your animals look different again, and will sometimes affect behaviour.
