The prince was asking for a sheep. The used word "sheep" (french
"mouton") does not imply any gender. When the pilot drew one with horns,
I was a bit surprised to see {DIj} used with the object being a thing whose representation was to be drawn on paper.
When I heard {DI'raq yIDIj}, I thought the prince was asking the pilot to apply paint to a sheep. Actually, wouldn't the object of {DIj} be a pigment stick, i.e., the command ought to have been something like {DI'raq DachenmoHmeH rItlh naQ yIDIj}? That can probably be shortened to {DI'raq yIchenmoH! yIDIj!} and finally just {DI'raq yIDIj!} so it's probably fine.
Did Marc Okrand say anything about the (usual) object of {DIj}?
