Krusty-O's

Krusty-Brand Cereal (also known as Krusty-O's and KrustyO ' s) is a brand of breakfast cereal endorsed by Krusty the Clown which prominently features his likeness on the box. The real KrustyO's, sold by 7 Eleven, were produced by the Malt-O-Meal corporation.

Dangers
Krusty-Brand Cereal is the catalyst for the episode "'Round Springfield", when Bart swallows a "jagged metal Krusty-O" included in the box as a premium and is sent to the hospital. Later in the episode when Krusty holds a press conference to show that swallowing the jagged metal Krusty-O isn't dangerous, he immediately begins to gag before he is informed he swallowed a "regular" Krusty-O, which he claims must be "poison". At the end of the episode, another box of Krusty-Brand Cereal is shown with the promotion: Flesh-Eating Bacteria In Every Box!".

Other Brands
Another line of Krusty the Clown-endorsed cereal, Chocolate Frosted Frosty Krusty Flakes, was also featured on the show. The box exclaimed "Only sugar has more sugar!" It first appears in "Bart the Genius" as "Frosted Krusty Flakes" during which Homer remarks that, since it has made Bart so clever, Lisa should try some too. There are also many other Krusty-brand food products, including Krusty Brand Imitation Gruel, which was fed to Bart and Lisa at Kamp Krusty. The episode "The Old Man and the Lisa" in the twenty-first episode of Season 8, first aired by the Fox network on April 20, 1997 includes Mr. Burns, temporarily unemployed, shopping for Mr. Smithers' groceries. He is searching for a cereal to purchase when he sees Krusty selecting Krusty O's. He asks, "Can you tell me where they put the Burns-O's?" Krusty replies, "They don't put nobodies on cereal boxes!" Then, he notices the Count Chocula cereal and says "Hmm. I suppose this one looks a bit like me."
