UPDATED 3/23, 4:44 p.m. ET: Cinnamon Toast Crunch has responded to a claim from Jensen Karp that he found shrimp tails in his cereal. 

“While we are investigating this matter, we can say with confidence that this did not occur at our facility,” the company wrote.

Karp has since said that he’s getting the seemingly tainted cereal tested in a lab. The supposed shrimp tail will also be getting its DNA analyzed. 

See original story below.

Cinnamon Toast Crunch once prided itself on its slogan, “the taste you can see.” But nobody saw this one coming.

On Monday, Comedian Jensen Karp tweeted a photo of what he believes were shrimp tails in his beloved cinnamon breakfast cereal. He tagged parent company General Mills, to which it replied that it would report the incident to the quality control team and send Karp a new box, something he ultimately wasn’t in the mood for. 

Shortly after, General Mills wrote that the very-shrimp-looking things that Karp found in his cereal box were, interestingly, not deep-sea creatures but rather globs of cinnamon. 

“After further investigation with our team that closely examined the image, it appears to be an accumulation of the cinnamon sugar that sometimes can occur when ingredients aren’t thoroughly blended,” the cereal’s account wrote. “We assure you that there’s no possibility of cross contamination with shrimp.”

Karp disagreed, showing close-up images of what he believes to be sea food.

“Ok, we’ll after further investigation with my eyes, these are cinnamon coated SHRIMP TAILS, you weirdos,” he wrote. “I wasn’t all that mad until you now tried to gaslight me?”

Of course, Twitter wasn’t entirely impressed with the brand’s explaination either, and a barrage of memes and Cinnamon Toast clapbacks ensued. Sure, maybe you can see the taste, but you also couldn’t avoid the social media stir the back-and-forth caused.
