Cornfuffs

The titular food of Kirby's Cornfuffs. This was originally a misspelling of "Corn Puffs" but the non-canon page "Kirby's Cornfuffs Part 2" explains in the sidebar that the unique title was kept on purpose moving forward.

The Food
Apparently available at grocery stores, Cornfuffs is a bizarre cereal that most characters eat as a dry snack, described as being like "soft popcorn." It's apparently quite delicious, despite its horrific ingredients, as most characters fight over it at some point trying to obtain it, though Waddle De is unable to participate due to an allergy to popcorn (despite this, he seems very excited to end up being the one to possess it). It is apparently also fat-free, according to the box.

Ingredients
The only known ingredients are popcorn, hand lotion, and artificial flavoring. It is apparently fat-free.

Flavors
Only two flavors are mentioned. The "regular" flavor from Kirby's Cornfuffs Part 1, which tastes like chicken, and a pizza flavor mentioned in King Dedede Catastrophe.
