In this installment of the Bluebonnet Series, everyone's favorite curious armadillo learns about the Battle of the Alamo and the Alamo Museum.

When Bluebonnet comes to San Antonio, the first thing she wants to do is see the Alamo. While rummaging for a nice, big beetle to eat for dinner, she meets Digger Diller, who is old enough to be her grand-diller. He tells Bluebonnet the tale of his great-great-grand-diller's involvement in the Battle of the Alamo. Bluebonnet is fascinated by the enthralling story of Santa Anna, Jim Bowie, and William Barret Travis.

But Digger Diller has a surprise for Bluebonnet. After the battle was over, Great-Great-Grand-Diller found Jim Bowie's famous knife. The knife was passed down, diller to diller, until it came to Digger Diller. Bluebonnet is excited to think about how much it would mean to all Texans to have Jim Bowie's knife on display at the Alamo Museum! But Digger Diller isn't so sure; the knife is his family treasure, and Great-Great-Grand-Diller probably wouldn't approve of him giving it away.

Digger Diller agrees to donate the knife, but after Bluebonnet's plan goes awry and the knife is nearly lost, Digger Diller begins to regret his decision. After this adventure with her new friend, Bluebonnet will always "Remember the Alamo!"
