HAPPY
This means that you’re “feeding” I-DOG enough music and giving it the right amount of love and attention. You’re petting its head or nose the right amount of times.
NORMAL
This means that I-DOG is content. You’re “feeding” it enough music and giving it the right amount of love and attention. You’re petting its head or nose enough to keep it content.
BORED
This means that you’re not “feeding” I-DOG enough music or giving it enough love and attention and it’s getting lonely. Pet its head or nose and play it some music to get it out of this mood.
