(CNN) -- Pepsi and peeps are teaming up for a new cola that combines the two sweet flavors.
The companies say the new drink mixes the taste of Pepsi with the "Pillowy-soft and sweet" marshmallow flavor of peeps.
But you can't buy this new flavor. Pepsi is giving away three thousand packages of it through a contest.
All you have to do is post your favorite springtime activities on Instagram and Twitter with the hashtag -- hanging with my peeps -- and tag Pepsi.
Winners will receive a three-pack of mini cans in bright yellow, pink, and blue colors.
Pepsi says the new flavor could eventually be sold publicly if there's demand for it.
