DeviantArt Description:

Just got yet another Equestria Girls image in the bag! :-)

In this one, the Girls go into cyberspace - and even the interior of a computer! The tsleportation also transformed their bodies (except their heads and necks; those remain unchanged); they've become digitized! Their new bodies one-piece outfits that don't come off when they're in the computer world; these new outfits are actually their cyberspace skin (the looks actually move and feel like skin); these new bodies (not their heads and necks since they didn't transform) even glow. Not to mention, the new bodies are each girls' respective colors:

Twilight Sparkle: Purple
Sunset Shimmer: Red
Fluttershy: Yellow
Pinkie Pie: Pink (or Magenta)
Rarity: Indigo
Rainbow Dash: Teal (or Cyan)
Applejack: Orange
Starlight Glimmer: Green
Trixie Lulamoon: Blue

Looks like they're ready for an Internet adventure.

Note #1: This is a reference to Space Jam: A New Legacy, and Jumanji: Welcome to the Jungle.
Note #2: These colorful cyberspace outfits the Girls are wearing are references to TRON: Legacy (2010) and Green Lantern (2011).
