Oh the thinks you can think!
Book by Dr. Seuss, Project by Shoddow D. Andrus
Imagery is a authors or poets way of putting a seen in our heads using descriptive words.
a good example of this can be found in the book oh the thinks you can think. "You can think about Night, a night at Na-Nupp. The birds are asleep and the three moons are up."
you can imagine a night in a strange alien place cant you?
And lets not forget those fun, goofy pictures.
