Reply 2
From Starfy Wiki
Reply 2 (Japanese: おへんじ2) is an item in Densetsu no Starfy 2. Kyuuriore gives it to Starfy after he gives her the Letter 2.
In the story, Kuriore and two other Jellato Sisters, Kuriora and Kyuuriore were attacked by Puchi Ogura #4's fire-breath and separated. To know that they are well, Kuriore expects both sisters to leave a reply.
Both Reply 1 and Reply 2 (Japanese: おへんじ1) must be given to Kuriore to open the door that leads to the Nuku Nuku Fur Treasure.
