Flurry Heart

Baby Flurry Heart, also Baby-Prinzessin Flurry Heart or simply Flurry Heart, is an Alicorn foal and the newborn daughter of Princess Cadance and Shining Armor. She makes her debut appearance in the season six premiere.

Development and design
Flurry Heart's name was first revealed on a German Hasbro Newsroom website on January 21, 2016.

She resembles Evening starlite in pony type and coat and mane colors and shares her wing design with Twilight Sparkle and alternate-timeline Pegasus Pinkie Pie. Unlike the body design used for most infant ponies in the series, such as Pound Cake and Pumpkin Cake, Flurry Heart uses the body design previously used for Applejack's birth certificate in The One Where Pinkie Pie Knows.

On January 28, 2016, in response to a Twitter questioning of "the logic of cluttering things up with yet ANOTHER alicorn princess", Jim Miller said to "understand that I'm not the ONLY person making decisions. I have input but I win some and lose some."

Depiction in the series
Flurry Heart is first indirectly mentioned in the season five episode The One Where Pinkie Pie Knows, in which Princess Cadance and Shining Armor announce to Twilight Sparkle and her friends that they're having a baby.

Flurry Heart makes her first physical appearance in the season six premiere, her reveal being witnessed by the Mane Six, Princess Celestia, and Princess Luna.

Merchandise
A translucent mini-figure of Baby Flurry Heart is included in the upcoming Explore Equestria Crystal Empire playset. "The two-story castle set will retail for $39.99 and comes with Princess Cadance and Baby Flurry Heart figures, dress, tiara, earrings, comb, and other themed accessories. It features a rotating throne — a necessity for any true princess, obviously — and spinning crystal closets. Plus, a little press on the heart and the floor lights up with cutie marks!"
