Réécris ce texte en le commençant par once upon a time (il était une fois)

There is a frog who loves a princess . He keeps calling her. He thinks he knows her so well.
That's why he wants to marry her. But there is a problem: the princess can't see the frog because she spends a lot of time in her castle .She only goes out when it's sunny . But when the sun shines .the frog stays in the water.(Now we know why a frog can't marry a princess)

Once upon a time ..........
