This cereal came out as part of the promotion for the Simpson's movie. Back when they turned some 7-Elevens into Kwik E Marts. They had KrustyO's, pink Doughnuts, Squishees, and Buzz Cola (which Sir Mike got and gave one to me, and then I reviewed it!).
These KrustyO's tasted like stale Fruit Loops.
So not horrible.
I made a playlist of all my Simpsons-related videos!
Watch them all!
