(FOX NEWS) -- No, this isn’t a new flavor of cereal.

A man on Twitter claims that he found two unusual items hiding in his box of Cinnamon Toast Crunch: the empty shells of shrimp tails.

Jensen Karp, a writer and producer who has worked on such TV shows as "Unleashed" and "The Masked Singer," posted a photo of the strange find to Twitter on Monday, asking the makers of Cinnamon Toast Crunch about the alleged "shrimp tails in my cereal."

He concluded the tweet by confirming that this was not "a bit."

Cinnamon Toast Crunch responded, saying that Karp would be sent another box, while the incident would be reported to the brand's quality control team. Karp, however, said he wasn't sure he was "ready" for a replacement box.

Cinnamon Toast Crunch responded again, but this time denied that Karp had actually found sugar-coated shrimp tails.

"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 brand wrote. "We assure you that there's no possibility of cross-contamination with shrimp."

Karp fired back. "Ok, we’ll after further investigation with my eyes, these are cinnamon coated SHRIMP TAILS, you weirdos," he claimed. "I wasn’t all that mad until you now tried to gaslight me?" His post also included photos of the sugary objects sitting in his hands.

He later tweeted an image of a box of Cinnamon Toast Crunch coverd with sticky notes, reading "do not eat."

In a statement obtained by Fox News, a spokesperson for General Mills, which produces Cinnamon Toast Crunch, hinted that Karp's cereal may have been tampered with, but only after leaving the production facility.

"While we are still investigating this matter, we can say with confidence that this did not occur at our facility," said General Mills spokesperson Mike Siemienas. " We are waiting for the consumer to send us the package to investigate further. Any consumers who notice their cereal box or bag has been tampered with, such as the clear tape that was found in this case, should contact us."

Several Twitter users reacted to the Cinnamon Toast Crunch's account's initial response, with one user writing, "Wow, this is amazing, I never knew sugar and cinnamon together can entirely mimic the obvious appearance of a shrimp tail, complete with shell structures and sub dermal veins."

Another user asked, "At what stage in the accumulation process does cinnamon sugar grow veins?"

"Hypothetically speaking let’s say this guy has a shell fish allergy and you’re saying it’s an accumulation of sugar," added another. "Yikes guys!"
