Kaeru no Tame ni Kane wa Naru

Since they were small children, the young Prince of Sable and Richard, the prince of the Custard Kingdom, were rivals in fencing. However, Richard always bested the prince of Sable, who dreamed to beat him some day. One day, word reaches that the Croakian Army, led by Lord Delarin, invaded the peaceful Mille-Feuille Kingdom and abducted Princess Tiramisu. Richard immediately sets out to save the kingdom, followed by the Prince of Sable. With that, an adventure begins to save the Mille-Feuille Kingdom and Princess Tiramisu.

And frogs. A lot of frogs.

For The Frog The Bell Tolls (original title: Kaeru no Tame ni Kane wa Naru) is an action-adventure/RPG hybrid for the Game Boy, developed by Nintendo. It was influenced by their own The Legend of Zelda series, which inherited some elements of this game. The later released Links Awakening shares an engine with it and has a cameo by Prince Richard in a house full of frogs. Since then, For the Frog the Bell Tolls hasn't gotten much acknowledgment by Nintendo, but Dr. Arewo Stein managed to appear as a recurring NPC in Wario Land 4, and there is a sticker of the Prince of Sable in Super Smash Bros Brawl.

The game never got a release in America or Europe, but a complete fan translation exists.
