Patrick is a school-age penguin who turns pink overnight. He feels like he no longer fits in at school, so he journeys to the land of the flamingos. But he doesn't fit in there either, so he goes home. His friends all welcome him back and Patrick decides that being different isn't so bad after all.
This book is more about self-acceptance than being gay, but a hot pink colour for boys is associated with gays or sissies, plus Patrick's best friend, Arthur, seems to have an extra gleam in his eyes when Patrick returns. So I'll assign this one a GLBTQ tag. Preschool - Grade 3.
