Each summer, Azum takes a new class to learn a new skill. This time, he chose an art class that focused on painting. The class was intense because the teacher wanted them to be great artists at the end of the summer. Azum took the class seriously. He practiced daily on canvas using acrylic. The paint dried faster than oil paint because it had an artificial resin.

Azum painted the scenery around him from the beach to the trees. Each sky was made of tints of blue. Azum created the blue for the sky by adding white into a darker blue. He was even able to blend the light blue with white so that there was no clear division between the colors. He did this every day. By the end of the summer, he was one of the best students in the class.
