Clurken is a large robot several times of Sonic's size. It resembles a large jellyfish that has a lavender body with two yellow cylindrical sections and in between, a section of Clurken's body has red cores embedded on it. It is surrounded by a large hemisphere-shaped dome that appears clear although small areas of it can flash with multiple colours. Attached to its main body are several white tentacles each with a lavender nozzle at the end.
Chaos Emerald Saga
Clurken was ordered by Dr. Eggman to attack Sonic and his friends when they were diving underwater in search of a Chaos Emerald and refused to give it to the doctor. Taking advantage of the underwater drag limiting Sonic's running speed, Clurken was able to easily knock Sonic with its tentacles and torpedos. When Sonic then tried to grab one of its tentacles, Clurken just simply flung him up into the surface, taking the fight out there. However, Sam Speed appeared and got Sonic to waterski out of Clurken's grasp. The robot tried to attack Sonic with torpedos but missed and then was defeated by Sonic using his Ring-powered Spin Attack.
