Hint Memo 2
Hint Memo 2 (Japanese: ヒントメモ2) is an item in Densetsu no Starfy 2. It is found in Pitch Dark Cave (Stage 6-5). It is one of three notes that contain a phrase. The phrase for Hint Memo 2 is 'freshwater clam' (Japanese: シジミ). When Starfy obtains all of the Hint Memos, upon returning to Moe he will have to pick the correct password from the Hint Memo phrases to open the red, green and blue doors set up by Puchi Ogura #6 that block Starfy's path. The other two notes are the Hint Memo 1 (Japanese: ヒントメモ1) and the Hint Memo 3 (Japanese: ヒントメモ3). Hint Memo 2's phrase is the correct password to open the door.
The Hint Memo 2 is found through the middle-most door north of the room containing the red, green and blue doors. It will be dropped by a Bu.
