Pepsi and Peeps are partnering for an unlikely pairing.

The companies are creating a new drink that mixes the taste of Pepsi with the “pillowy-soft and sweet” marshmallow flavor of Peeps.

The special product can’t be bought though.

Pepsi is giving away 3,000 packages of the new flavor through a contest.

Those who want to try the new product can post their favorite springtime activities on social media with the hashtag #HangingWithMyPeeps and tag Pepsi for a chance to win.
