Elmer and the Race [PDF ebook] 

The young elephants want to have a race to prove who is fastest, so Elmer and Wilbur organize a course. With each racer decorated a different color, they set off around the course and discover things about themselves-Blue is first, Orange is second, White is kind, Pink and Violet are funny, and Yellow is a cheat. Luckily Yellow also learns he is very good at saying sorry, so each young elephant gets a medal from Elmer.
