Annie said to the animals, “Please stand in a line.
I’m painting my alphabet. Come one at a time!
First Aardvark and Bear and Crocodile too.
Not yet, Zebra. I’m not ready for you . . ."

Annie wants to paint an alphabet using her animals, but Zebra simply can't wait until the end for his time to shine. Sneakiness, silly costumes and plain pushiness doesn't get him anywhere - but he has to learn to wait his turn!
