Risky Brothers (Zombies)

A duo of Zombie squirrels that served Perona. Their name was a play on the Japanese word for squirrel. They fought with an axe and a saw. The shadows that were being used to animate them were derived from the Rolling Pirates with the same name. They first appeared as the ones carrying the coffins that contained Usopp, Nami, and Chopper. While transporting the coffins, they accidentally dropped and opened the coffin containing Chopper, waking him, and were subsequently defeated by him. Later, after they recovered from his attack, they scurried off somewhere else to get their allies. They were later seen in the treasure room shocked by Nami's attack. They were interrogated by her for the location of the treasures previously stored there.

The shadows animating them were then later sucked out of them by their master, Gecko Moria. Without any shadows animating them, they returned to being stitched up squirrel corpses.

Trivia
