Now it so happened that on one occasion the princess's golden ball did not fall into the little hand which she was holding up for it, but on to the ground beyond, and rolled straight into the water. The King's daughter followed it with her eyes, but it vanished, and the well was deep, so deep that the bottom could not be seen. On this she began to cry, and cried louder and louder, and could not be comforted. And as she thus lamented some one said to her, "What ails thee, King's daughter? Thou weepest so that even a stone would show pity." She looked round to the side from whence the voice came, and saw a frog stretching forth its thick, ugly head from the water. "Ah! old water-splasher, is it thou?" said she; "I am weeping for my golden ball, which has fallen into the well."

不巧的是，有一次，小公主伸出两只小手去接金球，金球却没有落进她的手里，而是掉到了地上，而且一下子就滚到了水潭里。小公主两眼紧紧地盯着金球，可是金球忽地一下子在水潭里就没影儿了。因为水潭里的水很深，看不见底，小公主就哭了起来，她的哭声越来越大，哭得伤心极了。哭着哭着，小公主突然听见有人大声说：“哎呀，公主，您这是怎么啦？您这样嚎啕大哭，就连石头听了都会心疼的呀。”听了这话，小公主四处张望，想弄清楚说话声是从哪儿传来的，不料却发现一只青蛙，从水里伸出他那丑陋不堪的肥嘟嘟的大脑袋。
“啊！原来是你呀，游泳健将，”小公主对青蛙说道，“我在这儿哭，是因为我的金球掉进水潭里去了。”
