A is for Armadillo, but where are the rest of the animals in the ABC Book? They're all missing! It's up to Dora and Boots to jump into the giant alphabet book and help the little armadillo solve the mystery! They ride up the elevator at E and slide down a Slippery Slide at S. When they unzip the zipper at the letter Z, all the animals happily come tumbling out; it's a surprise party for Armadillo!
Tropes:
- Alphabet Song: The actual song is sung at the beginning of the episode; near the end, it is sung again with the animals in place of the letters they start with, referred to as the "Animal Alphabet Song".
- Portal Book: Dora and Boots go into the giant alphabet book to help Armadillo.
- Sentient Vehicle: Airplane who helps Dora, Boots, and Armadillo.
- Oddball in the Series: This is the third and final episode of Season 3 without star catching.
- Throw the Dog a Bone: Swiper swipes the stairs and throws them behind something that starts with "S".
