i couldn't figure out what the indicator with a neutral smiley stands for. whatever i did, the status went down. eventually the creature became sad and an icon that looks like either a nauseous face or batman's logo appeared. idk what i did wrong
i know i'm late but thats basically the entertainment ish meter, you need to play with the pet (3rd icon from the left at the top that looks like a pc or something) to fill up the bar, just click ctrl on the icon, whereafist will appear, and click ctrl again,, it's basically a rock paper scissors game.
