Description
''Warning: The following description is taken from a translation attempt of Sea Fairy Cookie's profile in KCR. Take it as you will.''

''The Red Dragon's heat began to slightly melt the cold curse that was placed on the Sea Fairy. However, because of a bitter heart, its soul was frozen and not so easily melted. If it weren't for the cookies' warm hearts, it would have chosen to remain frozen forever. Now they are fighting against the Red Dragon with frost and water, and the Sea Fairy Cookie has become a strong reinforcement fighter alongside the cookies. Behind their endlessly flowing hair, their eyes are still sad, but they still stands up to fate with intensity. So as to not disappear, they never let their sword leave their hand...''

Trivia

 * It is the 4th L Grade Cookie released in the game, and the 5th L Grade overall. The first was King Choco Drop.
 * It is also the first L Grade released thus far that is not associated to any episode, as they require Burning Hearts you can get from Rainbow Mystery Boxes in any episode and her Power + ability works in all episodes instead of being limited to one like King Choco Drop, Tiger Lily Cookie, Fire Spirit Cookie and Moonlight Cookie.
 * Its Power+ is the first Power+ among the L-grades to not produce mystery boxes in any specific episode; instead they recover the runner's energy after being hit by an obstacle.
 * The Power+ for this Cookie may have something to do with the Restoration Pendant of Water treasure, which also recovers energy after colliding with an obstacle.
 * It is likely that Sea Fairy Cookie is the Sea Fairy that Peppermint Cookie was referring to with regards to the legend of the Sea Fairy loving the moon.
 * It would probably relate to Moonlight Cookie  the moon.
 * In the last three floors of Tower of Frozen Waves, the background shows the Sea Fairy Cookie frozen while their hands are tilted upwards, being frozen while trying to reach the moon.
 * It is likely it used waves to try and reach the moon. The waves formed a tower when they were frozen - hence the creation of the Tower of the Frozen Waves.
 * They are the sixth Cookie in the game with an unique musical theme while running. The other Cookies are Rockstar Cookie, Mint Choco Cookie, Peach Cookie (during her Peachy Bo-Staff ability), Onion Cookie (during her Haunted House ability), and Macaron Cookie (during her Macaron Parade ability).
 * They are the seventh Cookie to have their signature background music while their Skill is in use, the first six being the aforementioned Cookies as well as Adventurer Cookie.
 * It is also seen in the sprite sheet that when Sea Fairy Cookie drops their sword, they become frozen. This might mean that the sword is part of their life force, and if they lose it they will freeze permanently.
 * The Red Dragon that was referred to in the description might take reference to the dragon from Dragon's Valley in the Flaming Dragon's Nest.
