Nemu Nemu no Mi

The Nemu Nemu no Mi, also known as the Nemu Nemu Fruit, can make anyone fall asleep. It was eaten by Noko in the game only.

Strengths and Weaknesses
This fruit's main (and only) power, as demonstrated by Noko, can hypnotize an opponent to sleep. With the seahorse flute's power to manipulate memories, the fruit can become much more powerful. The fruit almost beat the Straw Hat Pirates.

This fruit doesn't seem to have any specific weaknesses, aside from the standard Devil Fruit weaknesses.

But in the Anime, he didn't eat any fruit. He is a common boy who is being controlled by the seahorse flute. The flute can control peoples' minds, hypnotize people, and control memories. In addition, he is even seen under the sea. This is probably because the flute may give the user some abilities to fit its purposes. An example would be the ability to disappear in mid air. The flute is also an antagonist in the Ocean's Dream Arc special.

Usage
Noko mainly uses this power to put his opponents to sleep.
