Ronie G is a scam artist music producer who formerly discovered Jassie and Rocky, but then his scheme would've gone into action, if it wasn't for Lucky. He appeared in Dreams comes True.
Ronie seems to be a very outgoing person. He tries to act as if he knows a lot about the business so artists will sign him.
In Dreams comes True, Ronie sees Jassie and Rocky performing in Central Park. As we learn later in the episode, this was his shot to find his next victim. Ronie tells Jassie and Rocky he wants them to record a video. Excited, Jassie and Rocky accept. Soon, they find out that Ronie is a scam artist. He told Lucky he could produce him to be a successful whistle player. But once he got the money, he ran. So Jassie and Rocky leave him.
