Generate one image and save it in the current directory as sheet12.png.

Two reference images are in the current directory:
- reference-sheet1.png is the CHARACTER reference. Match its body shape, proportions, belly patch, outline and face exactly.
- reference-costumes-sheet11.png shows the costumes to reuse: the white ghost sheet (first figure), the witch hat and wand (second), the bat wings and the blank cream plank (third).

You may use your image-generator subagent for this. If you do, you MUST wait for it to finish generating, then check that sheet12.png exists in the current directory and is a real image, before you reply. Never reply while generation is still in progress. Do not search the filesystem or source code. Generate exactly ONE image, not several versions.

Prompt:

A character model sheet: the SAME companion creature shown four times in one horizontal row,
on one flat pale mint background. Leave a clear empty vertical gap between each scene —
nothing in one scene may touch or overlap the next scene.
Every figure keeps the rounded pebble-shaped body from reference-sheet1.png: short, wide and rounded, belly patch low on the front.
Left to right:
(1) CAUGHT PUTTING ON A GHOST COSTUME: it is halfway into a pure white #FFFFFF ghost sheet: the sheet is pulled down over the top of its head and one side, the rest still bunched up in its two short arms, the other half of its teal body still showing. It has just been caught: eyes glancing sideways at the viewer, a small guilty wobbly smile, a faint pale teal #D7ECE8 blush. Floating above its soft shadow.
(2) SCARED OF A GHOST: the companion with both short stubby arms raised over its eyes to hide, one arm lowered a tiny bit so ONE dot eye peeks out nervously, a small worried mouth, leaning slightly away. Close beside it (in the same scene, not touching it) floats a small cute simple ghost: a pure white #FFFFFF sheet shape with a wavy hem, two dot eyes and an open "boo" mouth, its little arms up, trying to scare the companion. The ghost is smaller than the companion and clearly friendly. Each floats above its own soft shadow.
(3) BAT, UPSIDE DOWN: the blank pale cream #FFF3D1 rounded plank with a dark outline at the top of the scene, completely blank. The companion hangs UPSIDE DOWN below it, the top of its head pointing down and its round bottom just under the plank. The top joints of its bat wings (very dark purple #2A1F45 with purple #6B4C9A inner panels) hook over the plank edge like a real bat's wing claws, and the rest of each wing folds half closed and wraps around the front of its body like a cloak, so only its upside-down face and a little of its belly peek out. Upside-down happy smile, dot eyes. NO ground shadow.
(4) WITCH CASTING A SPELL: wearing the purple #6B4C9A witch hat with the orange #F28C28 band. ONE short arm points the short thin very dark purple #2A1F45 wand forward and up; a burst of small warm yellow #F0C64B four-point sparkles shoots from the wand tip. The other arm is raised beside it, palm out, as if channelling the spell. Eyes squeezed into two short squinting curved lines, mouth a small tight determined line: concentrating hard. It floats above its soft shadow: NO legs, NO feet, NO sitting.

The character (match the reference image exactly): a small friendly non-human companion
creature. A rounded teal pebble-shaped body in deep teal #01796F, with a soft pale mint belly
patch low on the front, two small black dot eyes, a small simple curved smile, and two short
stubby rounded arms. It has NO legs and NO feet — it floats slightly above a soft pale
elliptical shadow on the ground.

Style: flat vector illustration. Clean uniform dark outline #113833 around the body and arms,
consistent weight. Flat solid fills only — absolutely no gradients, no shading, no texture,
no highlights, no 3D. Even ambient light.

Palette, exactly these colours and no others:
  deep teal #01796F (the body)
  pale mint #EAF6F3 (belly patch, flat background)
  pale teal #D7ECE8 (soft shadow)
  near-black green #113833 (all outlines, eyes, mouth)
  magenta #C42B60 (one tiny accent only, if any)
  warm yellow #F0C64B (one tiny accent only, if any)

Every character in the image must be IDENTICAL in size, proportion, body shape, outline weight
and colour. Only the pose, the arms, the facial expression and the prop may differ.

NO brown, tan, kraft, beige or any colour outside the six above — this includes paper bags,
flags, wood and cardboard, which must be teal or pale mint, never kraft brown.
The character has NO legs and NO feet in any pose, including sitting, jumping and walking.
No tongue. No nose. No ears.

No legible text, no numbers, no letters, no logos, no signage anywhere in the image. Any card,
box, screen or sign in the image must be completely blank.

COSTUME COLOUR EXCEPTION for this sheet only: the costumes, the second ghost, the wand and the plank may also use
these extra colours, and only on those items, never on the character's body: white #FFFFFF,
pale cream #FFF3D1, purple #6B4C9A, very dark purple #2A1F45, orange #F28C28. The character's
body, belly patch, eyes, outline and shadow keep exactly the colours above. Every costume item
gets the same dark #113833 outline. Cute, friendly and not scary in any way.
