Kuuigosu



Kuuigosu (クウイゴス) is a very buoyant wood, used by coated ships to ascend rapidly from the depths of Fishman Island. The speed of the ascent can be altered, depending on how many blocks are dropped.

It was first seen in Chapter 653, when the Straw Hat Pirates used it to travel up to the New World.

Trivia

 * The kana for "Kuuigosu" is backwards for "Sugoiuku" (すごい浮く, literally meaning "Amazing Float").
