The Mermaid is a character who aids Starfy throughout his adventures. She has appeared in every game in the The Legendary Starfy series so far. In the games, she allows the player to save their progress and heal all of the player's health. She also acts as a checkpoint, so if Starfy or Starly ever die, they can continue where the Mermaid last saved their progress. Mermaid is seen throughout various levels at different points, and is identified by her signature purple clam shell. She appears to be very nice, and is a good friend to Starfy and his pals. In the Game Boy Advance games, Starfy and Starly can save at the Mermaid by touching her shell. In Densetsu no Starfy, the mermaid appears in the background of the end stage sequence after first collecting 9999 Pearls. In the Nintendo DS games, Starfy and Starly have to approach the Mermaid and press X to save.
In Densetsu no Starfy, his image is 003, in Densetsu no Starfy 2 it is 013 and in Densetsu no Starfy 3, his card is 015.
In The Legendary Starfy, Mermaid can sometimes be seen if the player chooses to have Mermaid Gossip on his or her Nintendo DS's bottom screen. She will give Starfy (the player) tips and advice on the tasks at hand. She tries to encourage Starfy (and the player) to do their best and is always there to help out with her advice.
In Super Smash Bros. Ultimate, the Mermaid appears as a Spirit that boost the fighter's water & ice attacks powers. Her battle is on the rock at sea area of Wuhu Island against a Inkling who heals over time.
In Densetsu no Starfy 4, and the Japanese version of The Legendary Starfy the mermaid shouts "Hi hi!". In the English versions of The Legendary Starfy, this was changed to simply "Hi!"
According to Densetsu no Starfy 4's Secret Talk 12 item, there is a "Mermaid Fan Club". The membership number of the the Warp Jizou on the Hint & Items Screen is 10,989.
In Densetsu no Starfy 4, there is a glitch where saving at one Mermaid and moving towards another while the animation has not finished will show a glitchy animation for the other, even though Starfy or Starly did not interact with the other Mermaid. This is exploitable in Flourishing Desert (Stage 6-4).
None of Mermaid's voices between Starfy 4 and both versions of Starfy 5 are consistent, despite potentially being the same voice actress, Satomi Kōrogi.
