What it shows on the island

From holidays.yml:

Johnny in witch hat, jack-o’-lantern beside the palm, bats silhouetted against a full moon.

Sprite

Dimensions: 40 × 34 pixels. Anchored at island position (410, 298).

This is one of the four original Sierra sprites preserved from the 1992 game. existing_sprite index 0. The asset is the original full-island scene — Johnny appears in costume, the palm or message bottle is reskinned. The four originals are New Year’s Day, St. Patrick’s Day, Halloween, and Christmas; together they pin holiday IDs 1–4. See the holidays landing for the full 36-entry list including the 32 added by this port.

Palette

 #FF7A1A,  #000000,  #F0F0F0

Three-color hint from holidays.yml. This is a guide for the codegen step and the emblem authoring pass; the actual emblem samples from the shared 16-color CLUT, and the original Sierra sprites use the original game palette directly.

Algorithm

Fixed date — no computation; the HOLIDAY_KIND_FIXED dispatch in holidayForDate compares month and day directly. See Date-algorithm core.

Emblem

No 32x32 emblem entry; the visual for this holiday is the original Sierra full-island sprite, not a sheet emblem.
