Pearl Krabs

Pearl Krabs (born 1984) is a whale and the sister of Eugene Krabs Jr.

History
When Pearl was 9, her parents divorced. Her whale mother left Bikini Bottom for Bugtown, but her grandmother Betsy gave her some comfort, until she was killed by a villainous fish named Harold.

Pearl ended up abandoned in the ruins of their former house, with both her father and baby brother gone too.

This led to Pearl becoming a time-traveling supervillain with special burgers called "Water Patties" at her disposal.

She later hunted criminal Traumatized Meowcat in the 2040s, which led to her becoming a foe of the Space Myths.

She hated Ho-Sis, because at that time, he loved the time-traveling version of Betsy, who had not yet met Pearl's grandfather.
