Pearl Krabs

Pearl Krabs is one of the main characters in the series. She is a whale who lives with her father, Mr. Krabs, in a hollow anchor. Pearl loves tea parties, boy bands, and trips to the mall. She is one of SpongeBob's good friends. When she grows up, her father wants her to continue the family business by inheriting the Krusty Krab and becoming its owner.

Pearl was the second main character that series creator Stephen Hillenburg designed for the show. He was inspired to create a whale character while working at the Ocean Institute in California, where he tended to a whale skeleton exhibit and supervised whale watches.

The disparity in species between Pearl and Mr. Krabs has never been directly explained in an episode, but the official trivia book states that she takes after her unseen mother. Stephen Hillenburg was strongly against revealing the identity of Pearl's mom
