Morgana, sister of Ursula, almost steals the baby Melody from her parents, Ariel and Eric. To protect Melody, she's told never to enter the ocean, but by her 12th birthday, she's been swimming there for years. She discovers the magic locket that was to be her christening gift, which makes her visible to Morgana. Morgana tempts her by offering her fondest wish, to turn her into a mermaid; however, to remain a mermaid, she'll have to steal the magic trident from King Triton (who, unknown to her, is her grandfather). Meanwhile, all the sea creatures are searching for her. Along the way, she joins up with comic relief sidekicks Tip (a penguin) and Dash (a walrus). When she returns with the trident, Morgana's evil nature is revealed, and there is a massive battle of good and evil.

Ariel:
Where did you get this?

[holding a locket given to Melody by King Triton]


Melody:
I... I found it.


Ariel:
You went over the wall, didn't you?


Melody:
Actually, I went under it. I hate that stupid wall!


Ariel:
Melody, you know you're not allowed in the sea.


Melody:
But why? And why does that necklace have my name on it?


Ariel:
Melody, listen to me...


Melody:
You're hiding something from me!


Ariel:
You deliberately disobeyed me! I never want you going out there again! Do you hear me? It's dangerous in the sea!


Melody:
How would you know? You've never even been in it!
