Kaeru no Tame ni Kane wa Naru

In a faraway land, the two princes - Richard (from the Kingdom of Custard) and the main protagonist of the game (Prince from the Kingdom of Sablé) - have had a friendly rivalry with each other since childhood. They often compete against each other, even if it usually ends in a draw or a narrow victory. In fencing, however, Prince Richard is always the winner. One day, a messenger arrives from a small neighboring kingdom to warn the princes that the evil King Delarin has invaded the kingdom of Mille-Feuille and captured the beautiful Princess Tiramisu. In another cocky attempt to outdo the Sablé prince, Richard grabs a boat and races toward the kingdom. The Sablé prince stays behind and tries to catch up with him. On his journey, he and Richard (and many others) are transformed into frogs to reveal the true events of the kingdom. The game and its characters have been mentioned several times in the Super Smash Bros. series as trophies, stickers, ghosts and as the Sablé Prince's assist trophy. In these series, the game was officially romanized as "Kaeru no Tame ni Kane wa Naru".
