What is are krabby patties meatless?

As an AI language model, I don't have access to any insider information or confirmation regarding whether Krabby Patties are meatless or not. However, in the animated series "SpongeBob SquarePants," it's often implied that Krabby Patties are made with a secret ingredient that remains unknown to viewers. While the show does not explicitly state that the burgers are vegetarian or vegan, there are scenes where animals such as jellyfish and sea cucumbers enjoy the burger, which could suggest that it contains no meat. It is also worth noting that in the real world, Krabby Patties are not an actual dish and are therefore not available to the public, so it remains a mystery as to what the fictional burgers are made of.
