Velvet Cake (red unicorn) is the mare who took Bay in when she left Cloudsdale for Canterlot. Velvet is the original owner of Bay’s wedding studio, and who she apprenticed with before eventually taking over the business.
Twinklebell (blue unicorn) is Velvet’s wife. Velvet was unsure she would ever remarry after her first husband’s passing, (they were high school sweethearts) but the ever-dazzling and kindhearted Twinkle swept her off her hooves.
Though not biologically related, both mares love Bay Breeze dearly and consider her their own. They are extremely accepting and supportive of Bay’s recently rekindled relationship with her birth mom, Orchid Breeze.
More about Velvet and Twinkle when I get to them in the drawing queue.
