蝌蚪找媽媽的故事英文版如下：
Once upon a time there were small tadpoles swimming in a pond. They all wanted to find their mommies, but didn't know how. One tadpole said to the others, "I'll go and find my mommy too." So off it swam, but soon it got lost and didn't know where to go. After a while, it saw a big fish swimming by and asked, "Excuse me, do you know where my mommy is?" The fish said, "No, I don't know." Then the tadpole saw a frog hop by and asked again, "Excuse me, do you know where my mommy is?" The frog said, "No, I don't know either." The tadpole was feeling sad and confused.
