Kirby puts on a chef's hat and clangs a spatula & frying pan, and nearly everything within a limited radius is drawn into the cauldron to stew. After a short while, the characters that are sucked in and various items, mostly food items, are launched upward, causing about 24% and relatively weak knockback that may not generally KO those under 100%, though this can be helped by using the move closer to the blast lines. Its true strength is in its decent range against multiple foes, and the helpful items it produces.
This Final Smash also has the potential drawback of allowing those hit by the attack to use the items that come out with them. The other drawback is, if Kirby leaves any opponents out on the stage, they normally get first pick of the items that fall, because the others are sent out of the pot whilst Kirby poses to show the cooking is finished and cannot move until every item is spawned. Thus, Kirby sometimes cannot use the better items or destroy them before another player can. However, this may only be penalizing when a huge amount of items come out of the pot.
The more damage enemies have, the harder it is to avoid (i.e. if Kirby vs. Link, with Link at 200%+ damage, he will be sucked into the pot easier and from a farther distance). Cook Kirby can also suck in enemies through impassable walls, floors, stairs, etc.
The number of items produced by the pot and the damage players get is dependent on the number of things that get sucked into it; if nothing can be absorbed, nothing will come out. A character with a move that quickly produces objects (such as Pikmin Pluck or Fox's Blaster) can feed so many things into the pot that it can "max out," stopping it from sucking up anything else. A maximum of 30 items can be produced.
There is a chance that the Final Smash will produce only one kind of items (for example, only Bob-ombs); if this occurs, the move will not produce more items than the game can allow (if only Poké Balls are produced, only a maximum of three will appear even if more than three items are sucked in). If all items save for Smash Balls are disabled in a match, then the attack will not produce any items and will generally be rather pointless unless Kirby's opponents all have high enough damage.
There are many ways to avoid this Final Smash. Most of these require precise timing. The player can avoid it by:
In Ultimate, this move does not appear in Kirby's moveset, but Chef Kawasaki uses a nearly-identical move due to his identical abilities in the Kirby series.
The move is based on Kirby's Cook ability from Kirby Super Star and Kirby & The Amazing Mirror, usually obtained by Chef Kawasaki and occasionally Cookin. While not able to damage bosses like other one-time-use powers, it was able to suck in all enemies that appear on-screen to turn them into healing food items. This Final Smash also reflects Kirby's love for food, as he usually eats up enemies and gobbles food along his journeys, and has even been traveling to a mountain filled with gourmet goods in Kirby Super Star's mini-game, Gourmet Race.
Kirby in chef's garb. When Kirby throws on his chef's hat, a giant pot appears in the center of the screen. All characters, items, and even long-distance weapons are sucked into the pot. Once they've simmered a bit, food items equal to the number of things in the pot appear. Characters in the mix get blasted straight up out of the pot.
