Minigame
Minigames are featured often in the Starfy series. They are usually unlocked during the story.
Densetsu no Stafy
Minigames are giving to the player by allies. For example Tatsunomama gives you Sea Horse Kid Catch. You can also miss them and not get any minigames at all in the story. After you beat the first story you can access the minigames from the stage select screen, but you will only get pearls for winning if you play by visiting the character that gave the minigame. Going to the characters and beating the minigames on hard is required if you want to complete the Picture Book. There are 7 minigames total in this game.
Densetsu no Stafy 2
Unlike Densetsu no Stafy, minigames are unlocked by completing stages, but you start with one after unlocking Moe's House. The rest are unlocked by the time you complete the first story. Beating all the games on hard will unlock costumes. There are 5 minigames in this game.
Densetsu no Stafy 3
Minigames can be accessed at Moe's House after unlocking it. This is the first game that allows more players on minigames. Only one game pak is required. They are unlocked the same way as Densetsu no Stafy 2. Beating the games on hard unlocks costumes. There are 5 minigames in this game.
Densetsu no Stafy 4
There are no minigames in this game, but Spring of Love is kind of like a minigame.
The Legendary Starfy
Minigames can be accessed at Moe's Case. You start with Dumpling Master, the only minigame in this game that is 1-player only. The rest are unlocked by playing them with Mini G at least once. There are 5 minigames in this game.
