What do you mean by "fight peas if you have nothing to eat" and the last sentence "fight peas"

This online buzzword originated from a joke, which reads as follows:

A reporter went to the South Pole to interview a group of penguins?

He asked the first penguin, "What do you do every day?" ?

Penguin said, "Eat and sleep and fight peas!" " " ?

Then I asked the second penguin, and the penguin still said, "Eat and sleep and fight peas!" " " ?

The reporter asked other penguins in doubt and got the same answer, so he kept asking 99 penguins. ?

When walking next to the100th little penguin, the reporter went over and asked it: What do you do every day? ?

The little penguin replied: Eat and sleep.

The man asked in surprise, why don't you fight peas? ?

The little penguin curled his mouth and stared at the reporter: I am Doudou! ! ! !

With the popularity of the phrase "eat and sleep and fight peas", many peripheral products have appeared one after another. Small games, toys, stickers and even cartoons seem to have a great impact on people's lives.

In the current social environment, this sentence can be extended to doing nothing every day and being bored, which is also a direct reflection of the lonely and empty mentality popular on the Internet.
