In "SpongeBob SquarePants", why is Mr. Krabs' daughter Zhenzhen a whale?

SpongeBob SquarePants is the childhood memory of many people born in the 1990s. Although many plots are no longer remembered, there is still one issue that bothers everyone, and that is the relationship between Mr. Crab and his daughter. Obviously, Zhenzhen is the whale and Mr. Krabs is the crab.

Mr. Krabs, formerly known as Eugene Crab, owns a restaurant. Because of the secret recipe of the Krabby Patty, there were constant customers every day, and he became a well-known rich man in Beachcraft Castle. However, his nemesis, the rogue boss, still lives a poor life, so he is often ridiculed by Mr. Crab for his incompetence. In addition, Mr. Crab is still a very stingy person, and he will complain if he is charged even a penny less. It is also common to deduct the salary of two employees.

Mr. Krabs’ daughter is Zhenzhen, and her prototype is a sperm whale. Unlike Mr. Krabs, she likes to go shopping and spend a lot of money. On her birthday, Mr. Krabs throws her a very stingy party. For 16 consecutive years, I was laughed at by my friends and couldn’t stand Mr. Krabs’ stinginess. What she doesn't know is that Mr. Krabs loves nothing more than money. This love also involves fear. Because her ancestor was eaten by a whale, Mr. Krabs usually doesn't dare to mess with her.

Mr. Krabs is obviously a crab, why is his daughter a whale? This comes down to when Mr. Krabs was younger, and a few people should remember him serving in the Navy, nicknamed "The Real Golden Bell." At that time, Mr. Crab and Zhenzhen’s father, Lao Whale, were comrades-in-arms. They were sent to fight on the front lines. Unfortunately, Zhenzhen's father was shot dead and before his death, he entrusted his little daughter to Mr. Crab. After the war, Mr. Crab rushed to his hometown Zhenzhen.

Unexpectedly, humans are hunting underwater creatures. The old whale's wife was killed by a human harpoon, while Zhenzhen hid in her mother's arms and shivered. Mr. Crab saw this scene and quickly picked up Zhenzhen and ran away. Mr. Crab was worried that she would be bullied into an orphan, so he adopted Zhenzhen. She was still very young at that time and she couldn't remember these things, but it was always Mr. Krabs who grew up with her.

With the support of her father, Zhenzhen has a bad temper and often spits at Mr. Crab. But she didn't know how ruthless Mr. Crab was, and she was worried that her stepmother would hurt her, so she never got married and lived a poor life, so she worked hard to run the restaurant well.
