Dragon Quest: Shōnen Yangus to Fushigi no Dungeon

The game utilizes randomly generated dungeons and combat taken in turns.[2] Players must fight through different floors of enemies until they reach a boss monster, which they must defeat to advance through the story.[3] Combat takes place on contact with enemies, with no separate battle screen or menu system.[3] A new feature to the series is the "tension command", that allows players to build up attack power to deliver strong blows upon enemies, though the character cannot move in this state.[3] Later on in the game, and players can capture monsters with a special jug, and use them to attack opponents.[3] Players may keep three monsters in their possession at any one time, and can be taught to use special abilities by using items and through combat experience.[3] Monsters must reach level four, be given foods they like, and also a weapon before they will assist Yangus, and as they fight more and more, they will combine their strengths with other captured monsters.[3][4] Players can also utilize a farmhouse late game where monsters can be kept and bred to create new and more powerful monsters.[3] The game also uses cinematic and computer generated scenes with a comic-book style.[3]

The game centers around the character Yangus, who is a main character in Dragon Quest VIII, as a child.[5] Described as a "plump bandit", he becomes involved with his father Yampa's gang of thieves when a mysterious jug is brought home.[3][6] Though instructed not to touch the jug, Yangus does, and is sucked inside the bottle into another world called "Bottle Land".[3] Gelda, a female bandit from Dragon Quest VIII also appears in this new world, as well as Red, Morrie, Toruneko, and a new character named Poppy, and each begins to explore the dungeons of this new land.[2][3][6]
