I’ve already found it.
It’s Emma From South Korean CGI Animation Series: Robot Arpo.
Emma, who has a very strong smile, is a neighbor girl of the Diablo family.
I love Joey so much that I live in DeLavly 's house and I throw Joy into an extended love affair. It rushes to food with enormous food, and when it eats, the body temporarily becomes very huge. She is simple, ignorant, but she can not but love her purely!
