Original Description:
 
Non-player character for an ongoing FO:E project/RPG. Her name, GECK-O, is a nod to Fallout’s GECKs (Garden of Eden Construction Kits.) In FO:E, her name stands for Garden of Equestria Construction Kit - Organic. Ergo, an organic version of what are usually technological objects.
 
She’s been rescued by Team B, and belongs to the same triad as Double-Deck Cake (Pinkie Pie’s triad.) She’s a very cuddly pony, always keeping really close to the other member of her triad, Double-Deck. She’s also incredibly soft, as her coat, mane and tail are silky smooth to the touch (a call-back to her past.)
 
Her actual name is Carrot Cake.  
Her ‘past’ name was Silk Worm.
