I never understood why Pearl was a whale and Mr. Krabs's daughter all at once. My theory is that Pearl's mother (who was a whale) got involved with another whale, and broke up with said whale. Then I suspect that she got involved with Mr. Krabs, and after Pearl was born, either died or ran off with someone else, and left Pearl in the care of Mr. Krabs.
I'm noticing that various users will delete edits I've made. Not only is this frustrating, it's also annoying, because this means that (and I know you know who you are) you believe that I'm incompetent of performing to the best of my ability on here. When you're ready to apologize AND stop what you're doing, I'm ready to listen.
