If your adult character's band passes their judging, and gets a pro debut they can give peformances (three a day; once each at 5 PM, 6 PM, & 7 PM.) At 9:30 AM the next morning, the band manager will deliver their pay. If you're doing well, you can make 10,000,000 (yes: 10 million) gotchi points per day. Until then, you have to rely on hand-outs from the king or your character's parent (if you're on 2nd generation or higher.) Don't worry about your character starving to death, even teens & adults can survive on baby food & baby snack, but these won't fill more than 2 hearts.
