Kevin the Sea Cucumber
He tells SpongeBob that the way to find a queen jellyfish is to stand up in a tree and yell out a call, which is "Loser". Then him and The Jellyspotters go into a giant robot queen jellyfish to trick SpongeBob. But then the real King Jellyfish shows up and Kevin gets scared and starts sucking his thumb, saying "I want my mommy. I want my blanky." So SpongeBob gives the jellyfish a bubble shaped like pie and King Jellyfish goes away. The Jellyspotters want to make SpongeBob their new leader, but he refuses.
Kevin wears brown pants which he has labels for all kinds of stuff relating to Jellyfish, on the top of his head is a yellow thing (or like real sea cucumbers, a spike) shaped as a crown, although we soon find out that it really isn't a hat, it's part of his actual body. He wears black circle glasses and he's quite stubby and skinny.
Kevin thinks he is the best. He is actually a scared being, because when they all were in trouble, he just curled up and said, "Help me mommy, help me!!! I want my blankey!!! I want my blankey!!!!!". Kevin was the inventor of Jellyfish Sting Ointment Repellent (seen on a giant billboard in Jellyfish Fields). Kevin turned out to lie about himself, and he was really making a hoax. He usually is a target of Jellyfish to be stung.
- Kevin is a sea cucumber, and sea cucumber is the part of an animal group called echinoderms (animals that evolved with bilateral symmetry).
