Cook Kirby (コック Kokku, Cook) is Kirby's Final Smash, where he boils his opponents in a large pot of soup. 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.
There are many ways to avoid this Final Smash. Most of these require precise timing. The player can avoid it by:
 Description from the Instruction Booklet
Whip out a big pot that sucks in enemies and items. After boiling everything, the pot explodes, blasts away enemies, and leaves behind a few items.
 Trophy Description
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.
The move is based on Kirby's Cook ability from Kirby Super Star and Kirby and the Amazing Mirror, usually obtained by Chef Kawasaki. While not able to damage bosses like other one-time-use powers, it was able to suck in all minor enemies that are 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 minigame, Gourmet Race.
