Ordeal of Swamp

The Ordeal of Swamp (沼の試練, Numa no Shiren) is lead by Gedatsu, and it's survival rate is 50%, but only due to his incompetence. Otherwise, it would be 5%. The only Straw Hat to come here was Chopper, who managed to defeat Gedatsu.

The area is filled with sinking clouds, making it difficult to navigate around.

Gedatsu creates purple clouds and he tries to toss it on someone's head. The cloud can cause whoever is in it to drown since clouds are made of water. It is hard to get the cloud off your head because it isn't solid.

In the English version of Pirates Carnival and FUNimation's edited-for-TV dub, it's called the I.Q Swamp Test.

First Appearance: Chapter 251; Episode 164
