"Foals"

"Foals" is an unreleased prototype series that was advertised back in 2012 but never saw a full release.

Only a few trial sets were printed at The Bella Sara Company in 2013 before the company ceased operations in June. Several of these trial prints have managed to make their way into the hands of very few collectors making them some of the rarest cards in the Bella Sara franchise.

The creator of Bella Sara, Gitte Odder Brændgaard, states that she hopes to offer "Foals" for sale someday.

In 2016, the card design from "Foals" was repurposed as promotional material for the "Foals - 2017 Promos" series.

Appearance
"Foals" cards are light pink cards with a brown hummingbird in the upper left corner. In the upper right corner of each card is the royal crest of the herd an individual foal belongs to.

The cards are printed on thicker cardstock similar in thickness to the original "Bella Silver" series.

Although card numbers state that there are a total of 55 cards, only 45 cards were known to be printed.

Trivia

 * This is the only Bella Sara series that does not include Bella herself! However, she does return in the "Foals - 2017 Promos" series.
 * Although no artist credit is given, the foal cards for Fiona, Jewel, Nike, and Thunder appear to be drawn by artist Spoops as she had posted similar designs of Fiona and Bella on her Facebook account.
 * The hummingbird that appears on the upper left corner of each card is the exact same hummingbird that appears on Hummingbird's "Royalty" card.
 * Brine's card uses the crest of Herd Bellasara instead of the proper crest of Herd Islandar.
 * Given that Calyx and Briar are present, it is assumed that Petal's card is 32/55, although only a low resolution image of her card exists.
