The Armadillo from AmarilloPaperback, 31 March 1999

Sasparillo, an armadillo from Texas, leaves his home to find out where on Earth he is, and with the help of a golden eagle, he discovers where he lives--in a city, in a state, in a country, on a continent, on a planet, in the solar system, in the universe. Along the way, Sasparillo learns about geography, history, the environment, and animals native to Texas.
