Jethra is a character that only appears in the episode "Chum Fricassee."
Jethra is a dark purple fish with light teal fins. He is wearing ratty dark green overalls. His left tooth is shorter than the right one. He is also wearing an old dark brown messy hat.
Jethra was first seen eating at the Krusty Krab and Mr. Krabs thought he was eating a Krabby Patty. When Jethra turned around, Mr. Krabs was shocked that he was eating Chum Fricassee. Jethra then told Mr. Krabs that there weren't any open tables at the Chum Bucket so he had to get his order to go. He even got Squidward Tentacles to sign his order.
