mood orb thing

The orb thing that floats around this lil guy is somewhat affected by mood and emotions.
It can change color, position, shape, size, etc.
It's only an indicator though, so it's also changed by will. Just because the orb is small doesn't mean it's sad or in distress. It just means that it's most likely that they are.
Emotions can be hidden by will.
