Nature gives us many signs that the spring season is upon us. Flowers bloom, snow melts, birds sing and, who could forget, Peeps make their annual return to grocery store shelves.

The marshmallow treat is most widely recognized for its distinct chick and bunny shapes, but this year, Today reports, Peeps will appear in an a new form as the company is collaborating with Pepsi to release a limited-edition PEPSI x PEEPS cola.

In a PepsiCo press release, Todd Kaplan, the vice president of marketing at Pepsi said, “After what has been a very difficult year, many consumers are looking for new things to smile about. So, to celebrate the start of springtime, Pepsi collaborated with Peeps to develop a limited batch of its first-ever marshmallow cola.”

Kaplan added, “We know our consumers love our limited product drops, and we believe that Pepsi x Peeps will deliver an iconic and delicious pairing that has the potential to become a fan favorite.”

Popsugar reports that Peeps has a long track record of working with other companies. Previous collaborations include brands like Crocs, International Delight, Oreo and Kellogg’s. 

What Peeps-flavored Pepsi tastes like

An a review for Thrillist, Kyler Alvord describes the limited-edition Peepsi as “sweeter than standard cola” but “less sweet than you might expect from a dessert-flavored soda.” He added, “If it didn’t taste sweeter than normal Pepsi, it wouldn’t taste like Peeps, which is basically pure sugar. Considering the mission at hand, Pepsi’s food scientists did a great job at embodying Peeps without overdoing it.”

How to get Peeps-flavored Pepsi

Popsugar reports that customers will not find the spring cola on the shelves of any grocery store, and that the only way interested parties can get their hands on a three-pack of the beverage is by entering a social media sweepstakes.

The sweepstakes began March 25 and will run for an undisclosed limited time, People reports. According to the site, it is unclear precisely how many packs of the beverage will be handed out, though the companies did announce that 10 grand prize winners will be selected to receive a package of PEPSI x PEEPS drinks.
