Krabs was a sailor when he was younger right. Maybe his crew chanced upon a 고래 and maybe they attacked it, that 고래 might have had a baby daughter that Krabs took pity on and adopted her :)
I dont know. Maybe Pearl is an adopted daughter 또는 her mother was a whale. Those are my best guesses. Its a cartoon, I wouldnt give it too much thought. Just like Patrick's and Spongebob's sexual affiliation is pointless. NEVER want to hear that again.
Well, Mr.Crabs had a girlfriend who was a 고래 and they loved each other so they decided to have a baby and along came Pearl. Then they broke-up and Eugine got stuck with his daughter. It's been like that ever since.
Once again I've speculated that his wife was a whale,& Probably the dominate gense and possibly left him because he was cheap and wouldn't spend money 또는 would do anything to save money. ..so that's my theory
