The Idea

The catch is a con — and only we're in on it.

Two American fishermen cast their bait and wait, sure they're about to land a big one. What they can't see is the punchline: below the surface, a tuxedoed crab waiter is calmly lifting their bait off the hooks and plating it for two fish diners at an underwater restaurant. He tugs the empty lines to fake a bite, the men reel in fast and excited — and pull up nothing but bare hooks. The whole joke lives in dramatic irony: the audience sees the heist, the fishermen never do. It ends on their deflated, baffled faces — and they never laugh. No dialogue, SFX only.

The whole trick

Split the world in two. Sell honest hope on the boat and a confident con underwater, then let the empty hooks connect the two. The audience knowing more than the fishermen is what makes the ending land.

Workflow at a glance

Four steps, start to scroll-stopper.

01

Design characters

Lock the two fishermen and the crab waiter as references.

02

Build key frames

Three stills: the cast, the free dinner, the empty hooks.

03

Animate in Seedance 2.0

Feed refs + master prompt, render 9:16 at 15s.

04

Polish & post

Layer SFX, add the title card, publish to Reels.

1
Step One

Character reference images

Consistency is everything — the two fishermen, the crab and the boat must read identically in every frame, above and below water. Lock clean references in Nano Banana (Gemini) or GPT Image, keeping left/right positions and outfits fixed, then upload them all into Seedance 2.0. Because the story crosses the waterline, keep the boat and the restaurant table consistent too.

The Crab Waiter

The Crab Waiter

The con artist

A charming red-orange crab with expressive eyes on stalks, two large front claws and small walking legs. Black waiter vest, white shirt front, burgundy bow tie. Handles everything with his existing claws — no human hands or extra arms.

The Fish Diners

The Fish Diners

The paying customers

Two colorful fish customers hovering at opposite sides of a small round table on the sandy seabed — cream tablecloth, two plates, a glowing pearl centerpiece. They lean toward their meals with delighted expressions as the crab plates the stolen bait.

Delighted · patient · well-served

Pro move

Lock bait ownership to a side and never break it: the orange fillet is the left plate, the pink shrimp is the right plate. Tying each prop to a fisherman keeps continuity airtight when the camera crosses the waterline.

Step Two

Storyboard the cast, the heist and the empty hooks

Before you animate anything, lock the story as three stills. Using your locked characters as reference, generate the setup on the boat, the free-dinner heist below, and the empty-handed ending. If these three read at a glance, the video will too.

FrameWhat we seePrompt focus
CASTBoth fishermen at the railing casting in a coordinated move; the orange fillet and pink shrimp arc off the rods, two small splashes.Medium-wide boat shot, warm sunlight, honest hope on both faces.
FREE DINNERThe crab slides the fillet off the left hook onto the left plate and the shrimp off the right hook onto the right plate; the diners lean in.Medium shot, both hooks and plates visible, food moving hook → claw → plate, no teleporting.
EMPTY-HANDEDBoth men lift their rods to two completely bare hooks; excitement collapses into wide eyes and open mouths.Close two-shot on the boat, an empty hook in front of each man, the readable pause on disappointment.

Here's the prompt for the FREE DINNER key frame — the crab plating the stolen bait:

Key frame · FREE DINNER
[STYLE] Feature-quality Pixar-style 3D animation, rich turquoise underwater light with soft rays and drifting bubbles. 9:16.
[ACTION] The red-orange crab waiter — black vest, white shirt front, burgundy bow tie — uses one claw to slide the orange fillet off the left hook onto the left plate, and the pink shrimp off the right hook onto the right plate. Both hooks left visibly empty above him.
[FOREGROUND] One small round table on the sandy seabed with a cream tablecloth, two plates and a glowing pearl centerpiece; two colorful fish customers lean toward their meals, delighted.
[NEGATIVE] No human hands, extra arms or extra claws. No teleporting or duplicated bait. No text, logos or direct camera gaze.

Step Three

Animate in Seedance 2.0

With your characters and boat already uploaded as image references, set 9:16 · 720p+ · 15s · no subtitles, and paste the full master prompt below. The shot-by-shot timeline shows the six beats and five hard cuts — the complete prompt follows underneath.

TimeBeat
0:00–0:02.5The cast — medium-wide boat shot; both fishermen cast in a coordinated move, fillet and shrimp land with two splashes.
0:02.5–0:04Underwater reveal — follow the bait sinking on two lines; tilt down to the restaurant table; the crab looks up and smiles at the delivery.
0:04–0:08Free dinner — the crab slides the fillet onto the left plate, then the shrimp onto the right; both hooks left empty, the diners lean in.
0:08–0:09.5The trick — the crab grips each line above its empty hook, gives one firm downward tug, then releases both, smiling at the diners.
0:09.5–0:12The bite — both rod tips dip; the fishermen light up and reel fast; two completely empty hooks rise above the railing.
0:12–0:15Empty-handed — excitement collapses; the red-cap man sighs, the bucket-hat man shakes his head; hold the baffled faces. No laughing.

🎬 The 15-second master prompt

This is the whole thing — copy it, swap the con (a raccoon busboy on a picnic table, an octopus barista) and you have your own dramatic-irony heist series.

Master prompt · The Crab Waiter
[CONCEPT] Create a 15-second vertical 9:16 Pixar-style cinematic 3D animated fishing comedy. Two American fishermen cast bait from a small fishing boat. Underwater, a crab waiter removes their bait and serves it to fish dining at an underwater restaurant. He tugs the empty lines to fool the fishermen. They reel in excitedly, only to discover empty hooks. End on their surprised, disappointed reactions. They do NOT laugh.
[VISUAL STYLE] Feature-quality stylized 3D animation. Expressive faces, appealing proportions and detailed materials. Warm sunlight above water. Rich turquoise water, soft underwater light rays and drifting bubbles. Clear visual storytelling with brisk, readable action.
[FISHERMEN — LOCK IDENTITIES] FISHERMAN 1 (LEFT): An American man in his forties. Fair skin, stocky build, short brown beard. Red baseball cap, blue plaid shirt with rolled sleeves, tan fishing vest, khaki shorts and brown deck shoes. Positioned on the LEFT throughout the boat scenes.FISHERMAN 2 (RIGHT): An American man in his forties. Lightly tanned skin, lean build, clean-shaven face. Beige bucket hat, sage-green fishing shirt, navy shorts and gray deck shoes. Positioned on the RIGHT throughout the boat scenes.RULE: Exactly two fishermen. Each holds one fishing rod with one line and one hook.
[BOAT] A small white recreational fishing boat with blue trim, a low railing, two seats and a cooler. Floating calmly on open water near a distant coastline. Preserve the same boat and character positions throughout.
[BAIT] Left fisherman: one small orange fish fillet. Right fisherman: one pink shrimp. Exactly two bait pieces and two fishing lines.
[CRAB WAITER] A charming red-orange crab with expressive eyes on stalks, two large front claws and small walking legs. Black waiter vest, white shirt front and burgundy bow tie. Confident, efficient and mischievous. He handles objects with his existing claws. No human hands or extra arms.
[UNDERWATER RESTAURANT] One small round table on the sandy seabed, with a cream tablecloth, two plates and a glowing pearl centerpiece. Two colorful fish customers hover beside opposite sides of the table. The two baited hooks hang directly above the dining area. No written menus or signs.
[SHOT 1 — 0.00–2.50 · MEDIUM-WIDE BOAT SHOT] The two fishermen stand beside the railing. The orange fillet and pink shrimp are briefly visible hanging from their respective rods. They cast into the water in a coordinated movement. The two bait pieces land with two small splashes. Both men watch the water expectantly. SFX: rod swishes, reel clicks, splashes and gentle waves. HARD CUT.
[SHOT 2 — 2.50–4.00 · UNDERWATER REVEAL] Follow the two bait pieces as they sink on separate lines. Tilt down just enough to reveal the restaurant table and its two waiting fish customers. The crab waiter stands between the hanging bait and the table. He looks up, notices the incoming food and smiles as though a delivery has arrived. SFX: bubbles and muffled underwater ambience. HARD CUT.
[SHOT 3 — 4.00–8.00 · MEDIUM SHOT: FREE DINNER] Keep both hooks and both plates visible. 4.00–6.00: The crab uses one claw to carefully slide the orange fillet off the left hook and lowers it onto the left customer's plate; the now-empty left hook remains visible above him. 6.00–8.00: He removes the pink shrimp from the right hook and places it onto the right customer's plate; the right hook is now visibly empty too. The fish customers lean toward their meals with delighted expressions. Food moves physically from hook to claw to plate. No teleporting or duplicated bait. SFX: gentle bubbles, claw clicks and soft plate taps. HARD CUT.
[SHOT 4 — 8.00–9.50 · CLOSE MEDIUM SHOT: THE TRICK] The crab reaches upward. He grips each fishing line just ABOVE its empty hook, one line in each claw. He gives both lines one firm downward tug, then visibly RELEASES both lines completely. He looks toward the diners with a mischievous, satisfied smile. Both meals remain on the plates. SFX: two brief line-tension sounds and bubbles. HARD CUT.
[SHOT 5 — 9.50–12.00 · MEDIUM TWO-SHOT ON THE BOAT] Both rod tips dip from the tug. The fishermen's faces light up with excitement. They reel quickly and lift their rods, leaning back slightly in anticipation. The lines rise out of the water. By the end of the shot, two completely empty hooks hang clearly above the railing. SFX: fast reel clicks, taut fishing lines and dripping water. HARD CUT.
[SHOT 6 — 12.00–15.00 · CLOSE TWO-SHOT: EMPTY-HANDED] Keep one empty hook visible in front of each fisherman. Their excited expressions collapse. Eyes widen, mouths fall slightly open. They look from the empty hooks to each other. The fisherman in the red cap lowers his shoulders and gives a disappointed sigh. The fisherman in the bucket hat frowns and slowly shakes his head in disbelief. Hold their baffled, disappointed faces for the final second. Neither fisherman smiles or laughs. End on the boat, with no return to the underwater restaurant. SFX: water dripping from the hooks, a disappointed sigh and gentle waves.
[CONTINUITY] Exactly two fishermen, two rods, two lines and two hooks. Exactly one crab waiter and two fish diners. Keep left and right fishing-line ownership consistent. The fillet goes to the left plate; the shrimp goes to the right plate. Both hooks are empty after the serving scene. The crab releases both lines before the fishermen reel them in. The crab and fish remain underwater. The fishermen remain on the same boat. No extra claws, human hands, duplicated props or changing outfits. No direct camera gaze.
[AUDIO] SFX only. Waves, rod swishes, reel clicks, splashes, underwater bubbles, claw clicks, plate taps and a disappointed sigh. No dialogue, narration, music or laughter.
[NEGATIVE] No dialogue, narration, music or laughter. Neither fisherman smiles or laughs. No human hands or extra arms or extra claws on the crab. No teleporting or duplicated bait, props or characters. No changing outfits or character positions. No direct camera gaze. No return to the underwater restaurant after the ending. No text, captions, logos, watermarks or end card.
[EDIT] Exactly six shots and five hard cuts. Complete the entire story within exactly 15 seconds. Preserve a readable pause for the final disappointment. No text, captions, logos, watermarks or end card.

Step Four

Sound, title & publish

The render is 80% of it. These finishing touches are what make it feel like a studio drop.

SFX only — no music

Layer rod swishes, reel clicks and splashes on the cast · muffled underwater bubbles below · claw clicks and soft plate taps at the table · two brief line-tension sounds on the trick · fast reel clicks and dripping water on the reel-in · a single disappointed sigh at the end. No dialogue, no music, no laughter.

Studio title card

Open on your studio title: "THE CRAB WAITER" + subtitle "Cinematic 3D AI cartoon mini-story." Keep the render itself clean — no captions or logos baked in.

Publish for Reels

9:16, hook in the first 0.5s on the coordinated cast. Caption with a comment-gate: "Comment CRAB for the full guide."

Protect the reveal

Never cut back underwater after the ending, and never let the fishermen smile or laugh. The comedy only works if they stay in the dark and we stay in on it — one knowing grin from the boat kills the whole joke.
