I think it's just good quality. Buns, Patty, Pickles, टमाटर Sauce, Mustard, Lettuce, Tomato, Cheese And Mr. Krabbs is just teasing Plankton about a secret formula to the Krabby Patty.
Because I remember an episode that Mr.Krabbs wants to make sure his customers are eating grilled cooked Krabby Patties not machine processed Krabby Patties
Hm....well maybe it's something so complex that no one would think of it! LOL. Um.... well, maybe it's money.... It could explain the high prices for Krabby Patties.... Or.... uh.... I got nothing else!
LOL, My Brother's Watching Spongebob Right Now. But, I Thin It's Buns, Patties, Lettuce, Tomato, Onions, Pickles, Ketchup, Mustard And Their Secret Sauce!
