There could be trolls in a couple of streets.
They are big and say ugly things to you when you pass by, taking out some mood and energy from you in the process.
If you interact with them there are two options: Feed and Humanize.
- If you Feed a troll, you lose half your mood and half your energy, and the troll grows bigger.
- Humanize is grayed out, because you need the Impossible Achievement to do it.
And that's it.
