Oreo and Sour Patch Kids, which are Mondelēz sister brands, are also releasing a merch line to celebrate the collaboration, including a matching crewneck and joggers “snack suit” set, a bucket hat, socks, hair clips and a belt bag.

Oreo says this cookie is inspired by the Sour Patch Kids brand’s naughty playfulness, adding that this new cookie may visually resemble a Golden Oreo but is actually Sour Patch Kids-flavored with multi-colored flecks baked right in. The creme inside is also filled with even more confetti-like sour sugar bits, making for a taste bud party.

Oreo isn't the only brand coming out with bright new flavors for spring. Dr Pepper recently dropped the new Dr Pepper Creamy Coconut, available in regular and zero sugar versions, starting May 1.

First they’re sour, then they’re sweet, then they’re … a cookie?
