We had no idea these existed.

The arrival of Coca-Cola’s signature holiday cans, adorned with cute polar bears, has become synonymous with the holiday season. The family of bears made their debut in 1993, have taken on different looks throughout the years, and became the bears we now know them as in 2016.

2016 also marked the year that the company decided to add hidden images to the bears.

“We…wanted to embed signature Coca-Cola elements so the Coca-Cola polar bears could immediately be recognizable as our asset,” Frederic Kahn, design director of Coca-Cola, said in a statement.

It slipped by us last year, but now we can’t unsee it: the bears have bottle caps for eyes (and the edge of the angled bottle cap becomes their eyelashes), and bottle-shaped reflections on their noses. Check out the zoomed-in image below.

“The illustrations feel fresh and playful and capture special holiday moments of family togetherness,” Kahn said.

We love how subtle the elements are—it's a fun test to see if your friends can find them. And if you’re not a fan of Coca-Cola, the company has added a festive touch to some of their other brands, too. Sprite Cranberry and Sprite Cranberry Zero are back for the holidays for the fifth year in a row. A splash would be great in a holiday cocktail.

Coca-Cola can be used for more than just drinking, too. Try adding it to cake, or to carnitas
