My own opinion as to why Coco just doesn't lay money is because she wants to earn it herself, which makes any gift more meaningful. Coco may be crazy but she's also one of the most smart and moralistic Imaginaries around.
I'm hoping we do get to see her creator, the scientist will be there, but it's possible the scientist either brings along her creator, or said person just shows up later.
And if this were all real, I want you all to know that I would adopt Coco in a heartbeat. She's not one of my favorite characters for nothing.
