海绵宝宝反祖现象是第几集

是第54集。

It's episode 54.

This episode focuses on prehistoric times millions of years ago, as SpongeBob Squarepants, Octopus and Patrick, who stumbled upon wood that had been struck by lightning and burned, but they don't know it's fire, touch it with their hands, and get burned.

Later, they found that the things roasted by the fire seemed to taste better, so the three began to rob the burning wood, and everyone wanted to have it for themselves. The last rain destroyed the burning wood, and suddenly the three of them were dumbfounded, because they could not drill wood for fire at all, and they could only wait for the next chance lightning to hit the wood and burn. Because the discovery of drilling wood for fire and keeping kindling was many years away.

这一集主要讲几百万年前的史前时期，作为古代海绵宝宝、章鱼哥和派大星它们无意中发现被雷电击中的木头烧着了，但是它们不知道那是火，用手去摸，然后被烫伤。

后来它们发现被火烤过的东西吃起来貌似味道更好，于是三个人就开始抢夺那个烧着的木头，谁都想占为己有，最后一场雨把烧着的木头浇灭了，顿时它们仨傻了眼，因为它们根本不会钻木取火只能等待下一次偶然的机会雷电击中木头并燃烧，因为钻木取火和保留火种的发现还在很多年之后。
