Does anyone knows how to get any interactions besides the hormone granade? Or whatever it is called?

I wonder the same thing, I remember that there was once a build where you could do "you know" with the characters in the game. Something that was lost with the new builds, this April 3 there is an update, let's see what new features it will have.

Hi there, you are now able to fully interact with all the species on the island, they are also able to grab you themselves if you get too close to predators. All the interactions have been planned out, we are just now getting close to having a beta function of the game.
