Olivia is sleeping over at her Grandpa’s house, but she forgot to bring her favorite bedtime story “Goodnight Polka Dot Pirate.” Milli, Geo and Bot are on the case. They know a place where you can get any book you need – the Umi City Library! Umi Car zips them to the scene, where they find out how the library works and even get their very own library card. With a little tap dancing on the computer’s keyboard, they get the call number of the beloved book and traverse the vast array of bookcases and shelves to find it. Umi Car meets them at the check out desk, and the team gets the book to Olivia right before bedtime so Grandpa can read her to sleep with her favorite pirate adventure!
