One Piece Wiki

The Kuku Kuku no Mi is a Paramecia-type Devil Fruit that allows the user to turn objects into food. It was eaten by Streusen.[1]


  • "Kuku" is short for Kukku (クック?), the Japanese pronunciation of "cook".
  • In the official English translation, it is called the Cook-Cook Fruit.

Strengths and Weaknesses

With this fruit, the user has easy access to food to feed themselves and others just by transforming any object into food. The user does not even need to cook the food.[1] The user can also turn an object into food in order to make it less dangerous or otherwise more useful.[3]

However, while the food created by the user can provide nourishment, it apparently does not taste good, as Big Mom remarked, though that could just stem from Big Mom's very demanding palate.[4] Other than that, the user is still affected by the standard Devil Fruit weakness.


Sixty-three years ago, Streusen was seen making meat out of a log by cutting it, and was immediately able to eat the meat.[1] Streusen is very skilled in using his Devil Fruit, as he was able to transform an entire castle into food in an instant.[3]


Veränderung Gourmet.

  • Veränderung Gourmet (変化食フェアエンデルングルメ Feaenderun Gurume?, meaning "Transformation Food"): Streusen stabs his sword into an object and transforms it into food. It was first used to change the collapsing Whole Cake Chateau into a real sponge cake with whipped cream in order to save the people on it and the residents of Sweet City below from the debris.[3] Veränderung is German for "change". This technique is called Gourmetamorphosis in the VIZ manga.


  • This fruit bears similarity to several other Devil Fruits:
    • Both this and the Ato Ato no Mi can transform everyday objects according to the user's imagination.
    • The fruit is similar to the Fude Fude no Mi as both can create foodstuffs.
  • This is the first and so far only Devil Fruit with a name composed of a single katakana. In this case, Ku (?).
