Jethra is a dark purple fish with light teal fins. He wears ratty dark green overalls and an old dark brown messy hat. His left tooth is shorter than the right one. He mostly resembles a hillbilly.
Role in episode
Jethra is first seen eating at the Krusty Krab and Mr. Krabs thinks he is eating a Krabby Patty. When Jethra turns around, Mr. Krabs is shocked that he was eating Chum Fricassee. Jethra then tells Mr. Krabs that there were not any open tables at the Chum Bucket so he had to get his order to go. He even gets Squidward to sign his order.
In Croatian, his name means "Liver." Because of this, his name in the Croatian dub is "Jura."
