[DeepL Translation - needs review] Once the chairs are lined up, it's already a bus. I'm off! Boo boo! A rabbit got on. A bear got off, and a cat got on. All right! ......The world of imagination expands. A "playful" story by the popular duo. There is also a set of 3 books in a case.
(Translator: DeepL)
The book is fully written in hiragana with spaces between the words.
