Pokemon 3D Adventure 2: Pikachu no Kaitei Daibouken

Pikachu and its friends stop at a tropical island expecting nothing more than a peaceful break. Their plans change when Chatot discovers an old treasure map pointing beneath the sea toward Wailord's Tear, a mysterious site hidden inside a sunken pirate ship.

Curiosity quickly turns the vacation into an underwater expedition. Following the map means entering the wreck, dealing with the dangers surrounding it, and solving the mystery of the treasure before the group can return safely to the surface. For Pikachu and the others, a relaxing island visit becomes another adventure built on exploration and helping one another through the unknown.
