|Look at the monster's x-ray.|
The letter X affords one very few choices in a project like this. I suppose "x-ray" was about all I could come up with. What else was there? Perhaps "The xylophone is memorably used to evoke the sound of rattling bones in Camille Saint-Saëns' eerie Danse Macabre." But that would have been a little beyond me at that age, so I went with the tried-and-true "x-ray." As this drawing shows, my knowledge of x-ray technology derives almost entirely from cartoons.
