Chicka Chicka Boom Boom by Bill Martin Jr. and John Archambault is a lively and rhythmic alphabet book where all the letters of the alphabet race each other to the top of a coconut tree. As the tree gets crowded, it bends and the letters tumble down in a fun, chaotic crash. With its catchy rhymes and colorful illustrations by Lois Ehlert, the book is a playful and engaging way for young children to learn the alphabet.
