How to make an AI mermaid fantasy drama
Brief for AI Create: A mermaid fantasy: a young merfolk princess is sent ashore for one summer with legs and no memory of why; a lighthouse keeper’s daughter finds her on the rocks, and both worlds start looking for her; 8 short episodes, English dialogue, every episode ends at the tide line.
The choices that make it a sea kingdom
| Step 1 setting | Choose | Why |
|---|---|---|
| Scene Style | Undersea Kingdom | Coral and pearl: spiral-shell palaces, mother-of-pearl arches, kelp forests and giant anemones. |
| Costume Style | Merfolk | Pearl-and-shell tops or scale armour; a scaled tail with translucent fins; a pearl and conch crown. |
| Visual Style | Family 3D Animation, Watercolor Anime, Watercolor Storybook or Digital HD | 3D or watercolour suits the colour and light of water; live action works with a soft, dreamy grade (Soft Glow). |
| Target Region | Follow script | A fantasy kingdom has no real-world region; this keeps the names you chose. |
| Dialogue language | Any supported language | Spoken as each clip renders. |
All of this is written into the descriptions when the script is read, so choose it first. Why they are fixed afterwards · Every scene and costume style.
Two worlds, two looks, one character
The signature trouble of a mermaid story is the transformation. Do not make it two characters. Make it one character with two states:
- In Step 2, build the princess once, in her tail. Then add a second look for the shore: the same face with legs and a simple dress.
- Pick the right look for the segments where she is in the sea and for the segments where she is ashore.
- Write the change as an event in the shot where it happens (the tail falls away into legs as the wave leaves) so the next segment starts from the new look.
Costume changes and scene states · What the system keeps track of between segments.
The shore, which is not the sea
Pick shore scenes that give the two worlds a clear join, and give each its own scene card in Step 2:
- Mediterranean Coast — white walls, blue doors, stone steps down to a cove.
- Island Resort — white sand, shallow turquoise sea, boardwalks.
- Age of Sail Harbor — a wooden harbour and tall ships, for a period mermaid tale.
- Frozen Wilderness — for a cold northern sea.
Each segment stays in one place and one stretch of time; moving from the reef to the rocks is a new segment. A segment stays in one place and one timeline.
Keep it dressed, keep it kind
The content checks stop nudity and anything sexual. Give every character a full clothing description in Step 2: a bodice of overlapping pearl shells over a fitted scale top, a scaled armour vest with a coral clasp, a flowing tail of blue-green scales with translucent fins. A mermaid story is an all-ages story by tradition; keep it that way. If a clip is blocked.
Invent your own sea folk, sea witches and kings. Characters from a known film or adaptation can trigger the IP check.
An undersea scene, shot by shot
| Beat | Shot to adapt |
|---|---|
| The palace | [Shot 1] 4s: Wide shot, fixed camera. A spiral-shell palace on a coral reef, mother-of-pearl arches catching light from above, kelp swaying. @Nerea, in a pearl-shell bodice and a blue-green tail, floats at the foot of the steps. |
| The guard | [Shot 2] 3s: Medium shot. @Dorian, a merman guard in scale armour, blocks the arch with his spear held crosswise. |
| The line | [Shot 3] 4s: Close-up on @Nerea, lifting her chin. @Nerea (firm, quiet): Tell my mother I went by my own choice. (voice: Nerea) |
| The pause | [Shot 4] 3s: Close-up on @Dorian. He lowers the spear a hand’s breadth. |
| The tide | [Shot 5] 3s: Wide shot from the arch, @Nerea swimming up and away toward the bright surface until she is a small shape in the light. |

Story shapes that work
- The princess ashore: a stranger on land, learning stairs, doors and money.
- The bargain: a sea witch, a price, a clause nobody read.
- Two kingdoms: reef and shore, each sure the other started it.
- The lighthouse keeper’s secret: a human who has known about the sea people all along.
- The sunken ship: a wreck, a stolen map and a treasure that belongs to neither side.
