Muffy,
Phoebe Pietro, &
Skye (all of these are pretty obvious)
Amelia the snooty eagle (her house furniture & music (K.K. Condor) have a very tribal/Peruvian forest magical feel to them)
maybe
Ankha if you want the Egyptian symbols..(some people find Egyptian deities magical)
Lionel for your white-haired wise man.
Clay because he looks like a totem or tribal sculpture/artifact come to life
Drago the dragon
Ruby! the white rabbit reminds me of Alice in Wonderland, space, magic hats...all things magic & wonderful--a must!
Phil I had him move in by an accidental spotpass, and he is REALLY COOL & he looks great in person, red & blue feathers & has candles & a nice house with groovy walls & minimalist furniture with pretty things on top.
Vesta her house with the spinning wheel & sewing machine remind me of sleeping beauty, and somehow magic. Also her fluffy wool=clouds
Tia for some reason Teacups seem magical to me. They always appear in stories & fortune telling.
So far that's 8 female suggestions, and 5 male suggestions...hmmm you'd need a grumpy & sporty type...
Grumpy-
Static--the lightening bolt could be all sorts of magic!

David Bowie, Harry Potter, Zeus....
Roscoe- just look at him, he looks like a shadow knight. ("Shadow Knight" is a made up term by Munna.

)
Sporty-
Snake-his hood & cute face look like an imp! Cheeky little magic rabbit!
Sly- He looks like a true mysterious creature with a plant filled home & topaz eyes.
I hope this helps your quest!

Kiki is a great Halloween black cat.
That's a good idea too.

Magic always has black cats associated with it. (Kiki is also adorable.)
