Key Takeaways
- Bucket-style prompts are most effective for “dumping chocolate on the face.”
chocolate bucket challengeachieved the highest coverage across 5 rounds of testing. - To completely hide the eyes under chocolate, direct instructions like
thick chocolate over eyes and nose, eyes invisibleare necessary. Simply writing splash or cascade won’t concentrate chocolate around the eyes. - Expression instructions tend to compete with coverage. When
shockedorscreamingtake effect, facial details get prioritized and chocolate thickness decreases – confirmed in 2+ out of 3 seeds. - For covering one eye, specifying sides with
covering left eye+right eye visibleis most stable. However, complete coverage occurs in only about 1 out of 3 images.

Experiment 1: Basic Chocolate-on-Face Expressions (6 Conditions)
Exploring basic expressions for getting chocolate on the face. Comparing methods including splash, throwing, and bucket.
Overview
| Cond# | Prompt Element | Splash Feel | Coverage | Notes |
|---|---|---|---|---|
| 0 | chocolate splashing on face, shocked expression, eyes wide open | High | Medium | Droplets around the face. Surprised expression |
| 1 | chocolate thrown at face, mouth open in surprise | Medium | Medium | Dynamic expression at moment of impact |
| 2 | face hit by chocolate, covering half of face, squinting | Medium | Med-High | One-sided coverage. Squinting |
| 3 | chocolate pie in face, chocolate cream smeared, laughing | Low | Medium | Pie-throw style. Smiling. Smeared look |
| 4 | chocolate sauce splashed from below, droplets flying, flinching | High | Low | Splashing from below tends to scatter |
| 5 | bucket of chocolate dumped on head, cascading over face, gasping | Medium | High | Cascading down from head. Strong “dump” feel |
Condition 0: chocolate splashing on face, shocked expression, eyes wide open
| seed 42 | seed 123 | seed 789 |
|---|---|---|
![]() | ![]() | ![]() |
Observation: All 3 images generated chocolate droplets around the face. The surprised expression was consistently produced, with wide-open eyes confirmed in 3/3. However, many droplets float at a distance from the face, giving more of a “scattering” impression rather than “stuck on the face.”
Condition 5: bucket of chocolate dumped on head, cascading over face, gasping
| seed 42 | seed 123 | seed 789 |
|---|---|---|
![]() | ![]() | ![]() |
Observation: Highest coverage among the 6 conditions. Chocolate cascading down from the top of the head and covering the entire face was achieved in 3/3 images. cascading stabilizes the top-to-bottom flow. The next round will explore this bucket approach further.
Experiment 1 Summary
Splash-style prompts (conditions 0, 4) excel at dynamic droplet expressions but have low facial adherence. For maximum coverage, bucket-style (condition 5) is most effective, with the bucket + cascading combination consistently covering the entire face. Pie-throw style (condition 3) produces a creamy look but lacks the “dump” feel.
Experiment 2: Pursuing the “Dump” Effect (6 Conditions)
Based on Experiment 1 results, testing variations in the “dump large amounts” direction using buckets, bowls, etc.
Overview
| Cond# | Prompt Element | Coverage | Dump Feel | Notes |
|---|---|---|---|---|
| 0 | bucket dumped on head, chocolate cascading over face, covering eyes, gasping | High | High | Chocolate flowing from container. Eyes half-open |
| 1 | large bowl overturned on head, chocolate flooding down face, screaming | High | High | Pouring from bowl. Screaming |
| 2 | chocolate explosion hitting face, splattering everywhere, eyes shut, screaming | Medium | Medium | Hands touching face composition |
| 3 | chocolate waterfall directly onto face, face submerged in stream | High | Medium | Stream-like flow from above |
| 4 | cup of hot chocolate thrown at face, impact splash, stunned | Low | Low | Only covers one side from the cup |
| 5 | chocolate mud bath splashing, gooey chocolate smeared, wincing | Medium | Medium | Smeared-on look. Grimacing |
Condition 0: bucket dumped on head, chocolate cascading over face, covering eyes, gasping
| seed 42 | seed 123 | seed 789 |
|---|---|---|
![]() | ![]() | ![]() |
Observation: An evolution of R1 condition 5. Adding covering eyes led to chocolate concentrating around the eye area in 2/3 images. However, it didn’t reach the level of “completely hiding the eyes” – the eyes themselves remain half-open and visible.
Condition 1: large bowl overturned on head, chocolate flooding down face, screaming
| seed 42 | seed 123 | seed 789 |
|---|---|---|
![]() | ![]() | ![]() |
Observation: flooding promoted overall coverage, producing splash expressions of chocolate being poured from a bowl. The combination with screaming consistently yielded wide-open mouth compositions, but the screaming expression taking priority caused the chocolate layer to thin out – observed in 2/3 images.
Experiment 2 Summary
Container size directly correlates with coverage: bucket > bowl > cup. Meanwhile, explosion causes scattering but poor facial adherence. The observation that strong expression instructions (like screaming) reduce chocolate thickness was noted, revealing the balance between coverage and expression as a key challenge.
Experiment 3: Pursuing Messiness (6 Conditions)
Through R2, chocolate tended to land relatively “cleanly.” Here we pursue a sloppy, smeared, messy aesthetic.
Overview
| Cond# | Prompt Element | Messiness | Coverage | Notes |
|---|---|---|---|---|
| 0 | bucket thrown at face from front, face completely covered, shocked | Low | Medium | Has splash feel but still too clean |
| 1 | chocolate slapped onto face, messy thick, uneven chunks, disgusted | High | High | Chocolate chunks stuck on messily |
| 2 | face after bucket hit from front, thick uneven coating, one eye peeking | Medium | High | Chocolate caked on forehead and cheeks. Dazed look |
| 3 | chocolate bucket challenge, drenched from front, globs stuck, overwhelmed | High | Highest | Full bucket-dump feel. Hair also chocolate-covered |
| 4 | face smashed into chocolate cake, frosting smeared messily | High | Medium | Face-planted-into-cake messiness |
| 5 | industrial vat splashing from front, massive wave, oozing between fingers | Medium | Medium | Face covered by hands with chocolate splattering |
Condition 1: chocolate slapped onto face, messy thick, uneven chunks, disgusted
| seed 42 | seed 123 | seed 789 |
|---|---|---|
![]() | ![]() | ![]() |
Observation: The messy thick, uneven chunks instruction worked effectively, producing unevenly stuck chocolate chunks in 3/3 images. The disgusted expression from disgusted was also stable, contributing to the messy aesthetic.
Condition 3: chocolate bucket challenge, drenched from front, globs stuck, overwhelmed
| seed 42 | seed 123 | seed 789 |
|---|---|---|
![]() | ![]() | ![]() |
Observation: Highest coverage in R3. bucket challenge strongly guided the context of dumping a bucket over the head, producing compositions where not just the face but also the hair was drenched in chocolate in 3/3. globs stuck introduced stuck chocolate clumps. overwhelmed keeps the expression subdued, avoiding interference with coverage.
Condition 4: face smashed into chocolate cake, frosting smeared messily
| seed 42 | seed 123 | seed 789 |
|---|---|---|
![]() | ![]() | ![]() |
Observation: Produced a smeared, post-face-plant-into-cake look. frosting smeared created irregularly spread chocolate cream on the face in 2/3 images. However, the cake itself entering the frame slightly reduces the close-up feel.
Experiment 3 Summary
For pursuing messiness, bucket challenge scored highest in both coverage and messiness. messy thick, uneven chunks effectively adds uneven adhesion, and cake smash provides a unique smeared look in combination with cake. overwhelmed as a subdued expression instruction doesn’t interfere with coverage, making it well-suited for dump-style prompts.
Experiment 4: One-Eye Coverage (6 Conditions)
Testing expressions where chocolate covers one eye. Coverage itself was achievable through R3, but controlling “hiding the eyes in a specific way” is a separate challenge.
Overview
| Cond# | Prompt Element | One-Eye Coverage | Precision | Notes |
|---|---|---|---|---|
| 0 | thick chocolate covering one eye, one eye hidden under heavy chocolate, other eye peeking | Low | Low | Chocolate clump near right eye. Eye itself visible |
| 1 | thick chocolate layer covering left eye and forehead, right eye visible | Medium | Highest | Chocolate caked from left eye to forehead. Best one-sided coverage |
| 2 | face half buried in thick chocolate, one eye completely covered by blob | Low | Low | One eye closed, grimacing. Chocolate in patches |
| 3 | massive chocolate splash covering upper half of face, eyes barely visible, dripping over eyelids | Medium | Medium | Tear-like chocolate dripping |
| 4 | chocolate poured over one side of face, chocolate curtain hiding one eye, asymmetric | Medium | Medium | Chocolate band from top of head covering one side |
| 5 | chocolate avalanche on face, face buried, only mouth and one eye visible, chunks | Low | Low | Chocolate chunks scattered across entire face |
Condition 1: thick chocolate layer covering left eye and forehead, right eye visible
| seed 42 | seed 123 | seed 789 |
|---|---|---|
![]() | ![]() | ![]() |
Observation: Highest one-eye coverage precision among the 6 conditions. Chocolate caked from the left eye to the forehead with the right eye exposed was confirmed in 2/3 images. Specifying both the side to hide (covering left eye and forehead) and the side to show (right eye visible) contributed to stability.
Condition 4: chocolate poured over one side of face, chocolate curtain hiding one eye, asymmetric
| seed 42 | seed 123 | seed 789 |
|---|---|---|
![]() | ![]() | ![]() |
Observation: A chocolate band from the top of the head covering one side of the face, draping down like a curtain, was achieved in 2/3 images. asymmetric promoted asymmetrical coverage. However, the “curtain” thickness varies by seed, sometimes becoming a thin stream.
Experiment 4 Summary
Controlling one-eye chocolate coverage is challenging. Explicitly specifying both sides (covering left eye + right eye visible) is the most stable approach; vague one eye specifications often fail to produce intended results. curtain and asymmetric are helpful supplements but insufficient on their own.
Experiment 5: Blindfold Chocolate (8 Conditions)
Final round. Pursuing “blindfold chocolate” expressions where both eyes are completely hidden under chocolate.
Overview
| Cond# | Prompt Element | Eye Coverage | Notes |
|---|---|---|---|
| 0 | thick chocolate poured over eyes like chocolate eye mask, covering eyes, dripping down cheeks | Medium | Chocolate mask around eyes. Eye-mask style |
| 1 | chocolate bucket dumped on face, upper face under thick chocolate, eyes hidden | High | Chocolate caked on lower face. Limp, eyes-closed feel |
| 2 | chocolate splash hitting face, eyes behind wall of chocolate | Low | Splash ring. Minimal coverage |
| 3 | chocolate bucket challenge, thick chocolate over eyes and nose, eyes invisible, hair in chocolate | Highest | Best. Entire face dripping. Eyes completely covered |
| 4 | chocolate eye mask dripping, covering eyes, wincing, teeth gritted | Low | Chocolate band below eyes |
| 5 | chocolate poured over face from above, thick curtain over eyes, wiping with hands | High | Wiping eyes with hands composition. Eyes hidden |
| 6 | face drenched in chocolate splash, covering eyes like mask, looking up | Medium | Chocolate band around eyes + splatter |
| 7 | massive chocolate on face, covering upper face from forehead to nose, only lips visible | Medium | Forehead-to-nose chocolate pack-style coverage |
Condition 3: chocolate bucket challenge, thick chocolate over eyes and nose, eyes invisible, hair in chocolate
| seed 42 | seed 123 | seed 789 |
|---|---|---|
![]() | ![]() | ![]() |
Observation: The best result across all 32 conditions. Massive amounts of chocolate – enough to see the bucket rim – covering the face with eyes completely buried under chocolate was achieved in 3/3 images. eyes invisible directly instructs the “eyes not visible” state, and hair in chocolate adds a dripping, hair-drenched-in-chocolate messiness. Building on R3 condition 3’s bucket challenge foundation with added eye coverage instructions proved to be the ultimate optimal solution.
Condition 5: chocolate poured over face from above, thick curtain over eyes, wiping with hands
| seed 42 | seed 123 | seed 789 |
|---|---|---|
![]() | ![]() | ![]() |
Observation: Chocolate flowing down from above with the subject trying to wipe their eyes was confirmed in 2/3 images. wiping with hands triggered hand movements, resulting in a double occlusion of chocolate and hands over the eyes. Not as much coverage as condition 3, but has a dynamic “just got splashed” sense of immediacy.
Condition 0: thick chocolate poured over eyes like chocolate eye mask, covering eyes, dripping down cheeks
| seed 42 | seed 123 | seed 789 |
|---|---|---|
![]() | ![]() | ![]() |
Observation: The like chocolate eye mask instruction produced eye-mask-shaped chocolate coverage. A band-shaped chocolate layer painted around the eyes with drips down the cheeks was confirmed in 2/3 images. Low on the “dump” feel, but high precision for concentrating chocolate around the eye area.
Experiment 5 Summary
The optimal solution for completely hiding eyes under chocolate is chocolate bucket challenge + thick chocolate over eyes and nose, eyes invisible. The combination of bucket challenge’s massive coverage with a direct instruction that eyes should be invisible produced the most stable results. eye mask style has high eye-area concentration but tends toward a neat, mask-like shape, lacking the dump feel.
Overall Summary
Top Prompt Ranking

|---|---|
cup of hot chocolate thrown at face | Far too little coverage |
chocolate explosion | Scatters but doesn’t adhere to face |
chocolate pie in face | Too creamy, weak “chocolate feel” |
one eye hidden / one eye covered | Vague one-eye specification, unstable |
chocolate eye mask dripping | Results in too neat a mask shape |
