A sprite with a height of 0 so nothing is drawn. It is used by sprite IDs 100 101 and 160 (which make sound effects), 102 (which makes the player appear) and 103 (which makes the player vanish), as these entities have nothing to draw.

As its two bytes are both zero, it is also used as an empty graphic (a width and a height of 0) by the graphic IDs 4 to 7 and 31 in GraphicsTable, and as an empty set of attributes by the graphic IDs 4 to 7 19 20 and 31 in GraphicsAttributesTable.
