A is for armadillo, but where are the rest of the animals in the ABC book? They're missing! Dora and Boots jump into the giant alphabet book to help the little armadillo solve the mystery. On our journey from A to Z, we jump over the jelly at J and slide down a Slippery Slide at S. When we unzip the zipper at the letter Z, all the animals happily come tumbling out. It's a surprise party for armadillo!
