"Four pttle worms" 是四条蝌蚪的英文表达方式。
这个表达的起源可能来自于一首儿歌，其歌词是：
Four pttle worms
Crawpng in the rain
One crawled away
Then there were three
Three pttle worms
Feepng very blue
One wiggled away
Then there were two
Two pttle worms
Sunny day, yippee!
One wriggled away
Then there was one
One pttle worm
All alone
He crawled away
Then there were none
这首儿歌讲述的是四条蝌蚪在下雨天爬行，其中一条蝌蚪爬走了，剩下三条；然后三条蝌蚪感到很悲伤，其中一条蝌蚪蠕动着爬走了，剩下两条；接着两条蝌蚪在晴朗的天气里欢呼，其中一条蝌蚪扭动着爬走了，剩下一条；最后一条蝌蚪孤独地爬走了，最终没有蝌蚪了。
