Thankfully some of the creatures are much less evolved than you, equipped with only legs and mouths and as easy to eat as an apple on the ground. Most species that you encounter, however, are more advanced than your own, and in these cases it’s not advisable to go in chomping. Instead, change your “stance” from aggressive to friendly, and you’ll open a new batch of diplomacy actions such as sing and dance. Some species are inherently aggressive and will attempt to eat you, forcing you back to the nest to wait for a hundred million years of evolution and growth before you’re strong enough to take them on. Others enjoy a good song and dance and will be impressed by your creatures’ performances. This little minigame is the base of all diplomacy for future generations.
