It Smiles

You are placed in a dark underground maze, and your goal is to find the blue orb. While you are looking for this orb, entities roam around you. If you hear a sound, that means that an entity has seen you, and is currently chasing you. To lose the entity, you need to be out of its sight for 30 seconds straight.

There are animals about, a capybara, a cow and a horse. These are just stationary eastereggs that you can find.
