Book excerpt: A story about how good citizenship and a little consideration can make our world a joyful place for all. Sunnyville is the perfect place to live, until one day Rhino tosses a candy wrapper on the ground. "What?" he says. "It's only one." But soon, others start throwing their trash on the ground, too, and it begins to pile up. Giraffe doesn't want to look at the garbage, so he picks a flower from the park to brighten his home--but then everyone picks the flowers, and now there aren't any left. Soon things become messier, noisier, and grumpier. Can anyone save the day?
