This is a children's board book with lyrics from "Get on the Bus" and pictures of the cast in different dance poses.
I've heard of novelizaton of a movie. This is sorta similar, only it's a board-bookification of a music video.
Here's the season two version of Get On the Bus:
I watched an episode from season one recently and was reminded of the surreal dance sequences the Doodles broke into after singing Get On the Bus in each episode: hiphop, tap, tango, swing. The idea made sense on paper since we were pitching this as an educational show. But choreographing, rehearsing and shooting 26 unique dance styles turned out to be harder than I expected. Moe's ballet performance in "Keep Trying" is absolutely hilarious.
I decided to replace those surreal dance sequences with an extended version of Get On the Bus in seasons two and three. The show was weird enough and everyone wanted more of our biggest hit. Needless to say, this book does not include any of that.
