My Little Pony (mobile game)
Apple Pie is an available character in Gameloft's mobile game, which is the first time that she is explicitly identified by name and appearance. She was added to the iOS version of the game on June 4, 2014 and to the Android version of the game on June 10, 2014. Her in-game character model has a different eye color than in the show, while the game's icon of her, a loading screen of the game's, and a Gameloft promotional image use fanart of her with her in-show eye color and with her tail colors (not shown in the icon of her) patterned differently. The game depicts her wearing her bonnet from Over a Barrel, The Last Roundup, and Pinkie Pride.
