Sell. 

Greek orange moondancer (proud pose)

She is really pretty!

Her stars and hair look mexican to me too. Like moonbreeze suggested, could be a tail transplant & head swap. I don't have mexican firefly to compare the head and body colour, but I wouldn't think the head would fit together so well with mexican twilights body? But perhaps someone that has both could give it a try 

Thanks heaps for helping guys!  I am soooo excited!

I just found this list of mentioned places in G4, that I don't think made it on the Walmart map. It's from the mlp FIM wikia

**oops, just saw most of these are on the map**

Mentioned regions

Hoofington
Hoofington is a village mentioned by Trixie as the site of her alleged battle with an ursa; her story implies the town is near the Everfree Forest. The suffix -ington is derived from old English for "town". The name is quite similar to that of a political news website, The Huffington Post.

Fillydelphia
Fillydelphia is briefly mentioned by Princess Celestia in the episode Swarm of the Century. As an excuse for cancelling her visit to Ponyville, the Princess says she has to go to Fillydelphia in order to deal with an infestation of "incredibly bothersome creatures", presumably parasprites. It is mentioned again in A Friend in Deed as Cranky Doodle Donkey's previous residence. In It's About Time, it is mentioned when Rainbow Dash gives the report that nothing dangerous is coming from Fillydelphia all the way to Las Pegasus. In Hurricane Fluttershy, Rainbow Dash mentions that Fillydelphia broke the tornado wind speed record with a top speed of 910 wingpower. It is also mentioned in Games Ponies Play. Lauren Faust, the show's creator, mentioned in a comment on deviantArt that she wanted to name the main setting of the show Fillydelphia after Philadelphia where her family resides, but ultimately went with Ponyville.

Trottingham
Trottingham is mentioned in Stare Master, where Rarity is making 20 gold-lined gowns for ponies there, and later mentioned in Luna Eclipsed as Pipsqueak's previous residence. It is probably a portmanteau of 'Nottingham', an English city, and 'trot', a jogging speed for horses.

Las Pegasus
Las Pegasus is mentioned in It's About Time. It is referenced when Rainbow Dash gives the report that nothing dangerous is coming from Fillydelphia all the way to Las Pegasus. The name is a play on Las Vegas according to the episode's writer M.A. Larson.[3] In the original version of the map, it was spelled "Los Pegasus", with an "Applewood" sign placed next to it, which implied a Los Angeles / Hollywood reference.

Tartarus
Tartarus is a place mentioned in It's About Time. It's a place where evil creatures are held prisoner and guarded by the three-headed dog, Cerberus. Tartarus is from Greek mythology, being a deep dark pit below the underworld where many of the damned are imprisoned.

Baltimare
Baltimare is a city mentioned in It's About Time. It is referenced when Rainbow Dash gave a mini-report that a pegasus just came back from there, and there was no danger. The name is a play on the real life city called Baltimore.

Saddle Arabia
Mentioned in the episode Magic Duel, Princess Celestia arrives to Ponyville with two representatives from the region. The name is a play on the real life desert region kingdom of Saudi Arabia.

Hollow Shades
Mentioned in the episode Apple Family Reunion by Apple Bloom while she is rattling off town names. Not much else is known about the destination.

Galloping Gorge

Foal Mountain

Tall Tale

Mustangia
Mentioned in the episode Games Ponies Play by Ms. Peachbottom. In the episode, she tells Shining Armor that she is "just an ordinary wild mustang from Mustangia".

Also, from the new sea pony book -

"The underwater city of Aquastria, ruled by Princess Celestia's sea lion cousin King Leo, appears in the picture book My Little Pony: Under the Sparkling Sea. It is an underwater city populated by seaponies and mermares, as well as other sentient sea creatures; in the book, the main characters visit the kingdom. The seaponies are referred to as "cousins" of the land-based ponies."
