Why was this called "wonderlamp"? It would have worked out just as well if it was just lampmaus. Maybe magiclampmaus was what you thinking of. The face doesn't even look that much like a genie. It's more like a ghost. Maybe you could be both?
You can make up anything you want about them. I like the shading in the background. Purple just seems like an appropriate color for this setting. I don't know. Maybe I just think of Arabic royalty.
