Lampreys are creatures that only appear in the episode "The Sewers of Bikini Bottom."


The Lampreys are rather large in size and faded purple in color.


The Lampreys are first seen after Squidward pulls them out of the water when he and SpongeBob attempted to get Mr. Krabs' safe which contains the Krabby Patty secret formula. The Lampreys start to bite Squidward's hands and SpongeBob told Squidward to use his teeth to pull them off. However, this only made the Lampreys bite his eyeballs instead but, eventually, the Lampreys were pulled off for good.
