The Sunflower Vase (Japanese: ヒマワリかびん) is an item in Densetsu no Starfy 2. It is found in Stage 2-1 (Gluglug Lagoon) in the same room as the Pot of Roses and the Vase of Roses. When Starfy approaches one of these items, the game will ask whether the player wants to collect it.
In the story, Ruby asks Starfy to find her some furniture, including the Vase of Roses, the Coral Table and the Shell Chair. The Sunflower Vase is one of the wrong answers. If Starfy brings Ruby the Sunflower Vase, she won't accept it and the Sunflower Vase will no longer appear in the room.
