Translated a cute story from a book. Is it correct?
The story:
娃娃抓蛤蟆
小河流水哗哗哗,
来了一胖娃娃,
抓了八只大蛤蟆。
游来一群小肥鸭,
见了蛤蟆叫嘎嘎。
Boy catches frogs.
The water of the little stream rushes by,
(when) a little fat child came by,
(and) grabbed eight big frogs!
A group of little fat ducks swims by,
saw the frogs and said quack quack!
I added some english words to make the story sound better is this still in line with the original story?
