This article is related to a game, manga series or other media that has not been released outside Japan. The coverage here may differ from what it would be in an official translation.
The skull Prison Key (Japanese: ろうやのカギ) is an item in Densetsu no Starfy 2, found in Torrent's Waterfall (Stage 10-5). It is used to rescue Yakoukagami from her prison cell. In the story, Yakoukagami was trapped because she overheard the talk of Echigyoya and Puchi Ogura #10. She tells Starfy that the Prison Key is through the door to the left. Through the door, Starfy must push puzzle pieces into spots to match a picture above it. The pictures are, in order, a skull, a ship with Ogura's face on it and Puchi Ogura #10. Some of the puzzle pieces in the last puzzle are false. The Prison Key is found in the room after the last puzzle.
