The Oops! All Berries meme originates from a genuine limited-edition flavor of Cap'n Crunch cereal first released in 1997, which famously ditched the yellow pillows for only berry pieces. In the mid-2010s, the box art became a popular template for Photoshop artists who replaced the 'Berries' with various other items to signify a total lack of variety or an unexpected abundance of one specific thing. It is widely used across social media to joke about video game rosters, movie casts, or specific social situations where one element completely dominates the landscape, turning a marketing mistake into a universal symbol for oversaturation.
