Editing Melody of the Sea

The stage begins with [[Princess Peach]] and [[Stella]] arriving at a beach, where a mermaid concert would be held underwater nearby. After a short walk, they encounter a turtle, who had been rendered unconscious by a [[Sour Bunch]] merman. As a pair of mermaid [[Theet]]s tries to bring the turtle back in shape by singing, Peach uses the power of [[Sparkle]] on them to help them, with the healed turtle thanking Peach by offering her a ride on its shell. The transformation of [[Mermaid Peach]] can be found in the singer's cove, with the room being filled with water in the meantime while the cutscene goes on.

When Peach and the Theets try to perform, the lights go out, and when they turn back on, the [[Sour Bunch]] seems to have trapped the Theets in [[bubble]]s, which leads to Peach saving them using the transformation's power to acquire the help of nearby fish by singing. At the end of the stage, the player performs a song by holding {{button|switch|B}} while tilting {{button|switch|leftstick}} to the direction of the fish. Missing a full pattern will cause Peach to take damage. After the song is completed, the remaining [[Sour Bunch]] members will be defeated.

[[Sparkle Gem]]s marked with an asterisk ⁽*⁾ will always be obtained during regular gameplay.
