• Character: Omitsu / Lucille

• Episode: 14 – お願い!コーン守は人気がほしい / Those Transformin' Felines

• Medium: Hand-painted production cel on acetate, no background (although you can see my ceiling reflected in the cel).

• Layer Code: B-5 End marks it as the final animation layer in that cut.

• Studio: Tatsunoko Production (1990–1991 TV run)

• Status: Single-layer setup (no visible A/B overlap)

• Scene Context: This cel appears right as Omitsu imagines herself gazing lovingly at Nyanki #1, her face softening in a tender daydream before the scene cuts to reality.

• The accompanying genga includes original color codes for her palette (PP93, BG20, R80, etc.) — these notations helped colorists match tones frame-to-frame.

• The genga and cel are perfectly matched, showing her profile view and shy smile from the start of the fantasy sequence.

Traditional anime relied on hand-painted acetate cels to bring emotional scenes like Omitsu’s to life. For moments of imagination or introspection, directors often used:

• Softer color palettes and simplified linework to distinguish fantasy from reality.

• Background overlays (like the pink hearts seen here) to visually cue emotional shifts.

• Limited animation (fewer cel layers) to emphasize stillness and expression over motion.

Because these dreamlike shots were brief and expressive, the corresponding cels were often discarded or reused—making surviving examples like this one particularly rare and collectible.

• Character: Otama / Francine

• Episode: 25 – “かわいい?ヤッ太郎女になる / Gender Bender Butterflies! (Ending scene)

• Medium: Hand-painted production cel on acetate with randomly chosen painted stock background

• Layer Code: 34-84 (marked in upper-right corner)

• Studio: Tatsunoko Production (1990–1991 TV run)

• Status: Single-layer setup (no visible A/B overlap)

Cel animation is a traditional animation technique that involves hand-drawing and painting individual frames onto transparent celluloid sheets, called cels, and photographing them in a sequence, to create movement. The cels are layered over static backgrounds, with each cel representing a slight progression of movement, and when played back quickly, these frames create the illusion of a moving image. This method, made popular by Walt Disney Studios, was the dominant form of animation until the rise of digital animation in the late 20th century.  

How this works:

1. Pencil Key Frames: Lead animators drew the main poses on paper.

2. In-Betweens: Assistants added the transitional drawings that created motion.

3. Inking & Painting: Line art was traced onto clear cellulose acetate sheets (the “cels”) and painted on the reverse side to keep lines crisp.

4. Layering: Each character or effect element received its own cel layer – labeled A, B, C, etc. – and was stacked over a hand-painted background.

5. Photography: The composite stack was photographed frame-by-frame, producing the illusion of movement when played in sequence.

Because every cel represented a single frame, they are one-of-a-kind production artifacts—a direct slice of animation history.
