The Golden Eel is, as the name says, a golden eel that lives in a cave in Bikini Bottom. It just appears in the episode The Curse of the Hex. Madame Hag tells SpongeBob and Mr. Krabs to go into it's cave, to get a gold coin from it's body. They do as they are told because if they get the gold coin, Madame Hagfish would take the curse off of the Krusty Krab.
As the name says, the eel is big and has golden skin. He also has a lot of green fins on his back and has really sharp teeth. He is probably not very bright because of his expression on his face.
- He apparently has a business because SpongeBob got its business card from Madame Hagfish.
- SpongeBob thought the Golden Eel's lair was filled with leftover pudding.
