The Purple Frog (Hardcover) (ISBN-13: 9780995284197)

Hubert the frog is a smart, purple frog who is constantly teased by his classmates and harassed by his brother and his sister. They are all green and they make fun of Hubert because he is different. One morning, Hubert wakes up with a green spot on the middle of his forehead. Each morning after, another green spot appears. He covers them up because he knows the teasing will only get worse. Imagine being a purple frog with green spots! How will Hubert ever survive the humiliation? He doesn't mind being purple but maybe it would be easier if he was all green like everyone else.
