Necklace (item)
From Starfy Wiki
The Necklace (Japanese: ネックレス) is an item in Densetsu no Starfy 4, found in Coral Coast (Stage 2-1, map 4). It is a necklace belonging to Ruby. Ruby left this item behind while moving from a pink roofed house to a larger red roofed house and it got stuck in bark. Other items that were left behind are the Perfume, the Hand Mirror and the Compact Mirror. Starfy must ring one Coral Bell to reveal the Necklace but in order to get to it, Starfy must first ring four Coral Bells because some bark blocks the way.
