I don't like the Oops! All Berries cereal because a food made entirely out of berries (no cereal crop ingredients) doesn't count as a cereal, instead it's a fruit salad or a milkshake.
So there's a variety of captain crunch cereal that's "Oops all berries" where it's only the colorful pieces and none of the "normal" cereal pieces. So I believe this is a play on that
