Heart Gem

Heart Gems, known as Konpeitou, コンペイトウ in Japan) are special treasures Starfy collects in order to gain more health. In The Legendary Starfy, they appear in large blue treasure chests and appear as diamond-shaped gems embedded with a yellow heart-shape inside them.

In Densetsu no Starfy 4, they also appear with yellow heart-shape inside them but are more spherical and appear with various bumps on them attached at the edges, similar to the appearance of Japanese Kompeitō candy.

In Densetsu no Starfy 4, obtaining a Heart Gem adds ten health points on to Starfy and Starly's health. Unlike The Legendary Starfy, Heart Gems do not appear in blue treasure chests. Some appear through Tobira Majin, while others can be found prior to completion of the main game. Starfy and Starly begin with 50 health points, but collecting a total of 20 Heart Gems allows for a maximum HP value of 250 health points. Six of the twenty Heart Gems are purchased from Manianko's Shop.
