Dragon Quest Monsters
Cobi and Tara are both in a family of monster breeders who have come to the island of Greatlog to make a living by opening a monster ranch. However, there is soon conflict with the island's prince Kameha and a character from the original "Dragon Quest Monsters" named Warubou who is his assistant. Because of this duo's bad behavior, the island begins to sink, and Cobi or Tara must explore five different worlds to find magic keys, and the plug, to save the island. In the Nintendo 3DS remake, the citizens are disturbed by a new threat after the original story ends, with the siblings having to find the “Ultimate Key” to open the door to two new worlds called “New World” and the “Legendary Demonlords” with gigantic and powerful enemies.
