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.
