During the intro cutscene, the theme from the fourth opening of the One Piece anime ("Bon-Bon Blanco - Bon Voyage") with its lyrics is used the Japanese version, but is replaced with a made-up instrumental version in the European version. The ocean ripples shown on the "One Piece: Round the Land" titlecard are also slightly different in comparison.

Additionally, the part where Luffy and his friends are running towards the screen together is a reference to the fourth opening of the One Piece anime, where Luffy and his friends are walking towards the screen together.
