The objective and the development of the game are exactly the same, only that the action takes place under the sea, since a ghost managed to escape from Momo after winning the first part, reaching the ocean and possessing various marine animals. Momo fights enemies in five stages, each at a deeper level, against ghosts and possessed animals such as an immortal jellyfish, a bank of bogues, a vampire squid and an anglerfish, until reaching the final boss, which is an underwater volcano. This game includes two new movements: a circle, by which the player gets a shield, and a spiral, by which the player pushes back all monsters. The shield lasts for only one attack.
