Kevin C. Cucumber was the leader of the Jellyfish Spotters until the episode, "I'm Your Biggest Fanatic." He was speaking at a jellyfishing convention, in which SpongeBob and Patrick attended. SpongeBob was a big fan of him, and would do anything Kevin told him to do. One day, he invited him to go jellyfishing with the Jellyspotters. He tricked SpongeBob into thinking he could join their club if he passed certain tests, simply so that he could humiliate and belittle him. This seems to be a habit of his, as many of his biggest fans have ended up stranded in a crevasse at Jellyfish Fields because of him. SpongeBob later figured out Kevin's intentions, when he was chased by their robotic queen jellyfish. Kevin and his friends then taunted and made fun of Spongebob so badly by calling him "loser," but when a king jellyfish fell in love with the robotic queen and attacked them, Kevin proved to be a coward and admitted that he was only in the club for the fashion. When Spongebob managed to ward away the king, Kevin was ruined when the Jellyspotters ripped off his crown-like cranium and put it on Spongebob. Although SpongeBob left the club, it's unlikely Kevin retained leadership of the club, as he lost the loyalty of his teammates. Kevin has not been in any other episodes. He only appeared again in games.
