A green feathered serpent stretched across the frame, drawn in the Mesoamerican style: a scaled body with clawed feet, a crest of turquoise and gold plumes behind the head, a stepped tail rattle at the other end. Pale smoke curls around it and fills the space between the coils.

A wad3 file at 80x64 pixels, so on the wall it is 80 units across against a player height of 72 units, a wide panel rather than a tall one. The scales and smoke take 246 palette entries out of 256, close to the ceiling, and 49.3% of the frame is transparent, so the serpent keeps its silhouette without a backing rectangle. At 7,656 bytes it stays inside the 16 KB tempdecal limit. The archive carried two .url shortcuts alongside it.
