The giant eel guardian is a minion of the cave of wonders, who attacked Spongebob and Mr. Krabs after Abu touched the monkey idol's jewel. it's highly assured that It was killed after the cave collapsed for good. it is one of the things added in the remake of Spongebob and Friends meet Aladdin, cause when the origenal was made, this eel never at first exsited. it is also apparently the cousin of the golden eel, one of the villains from the spongebob episode, "The curse of the hex." like it's cousin, it appears tired and uninterested, mainly cause of it being sleepy or underused cause of the cave destroying most of the intruders.
