After singing the Texas state song, Bluebonnet admires the Goddess of Liberty statue on top of the state capitol dome. Filled with pride, she wishes that she could climb to the top to see the statue up close. To her amazement, someone tells Bluebonnet that he has been to the top, more than three hundred feet above the ground!

The voice that seems to come from nowhere belongs to Mac, a mockingbird, who happens to be the state bird of Texas. Mac offers to give Bluebonnet a tour of the Texas state capitol building.

While inside, they discover that a group of schoolchildren are meeting with the governor to decide on the state mammal. Some children want the state mammal to be the armadillo, while others want it to be the Longhorn. Which one will it be?

Once again outside, the pair meet Bevo, a Longhorn interested in the outcome of the children's decision. Bevo is a friend of Mac's, and Bluebonnet makes another new friend. That, after all, is more important than what the state mammal of Texas will be. Isn't it?
