What is shrek ketchup?

As an AI language model, I do not have access to current or updated information about Shrek Ketchup, however, in the past, it was a limited edition Heinz Ketchup product inspired by the popular animated movie series, Shrek. It featured a green color and was marketed towards children who were fans of the franchise. The ketchup was only available for a limited time and is currently no longer available on the market.
