My rating is based upon suitability for my 2nd graders and is basically just for me to look back on next year. It was a bit short and simplified for their liking although they did mostly like it, they are ready for something with a more complex story line and richer writing.

It would be a better read aloud for first grade or kindergartners.

It’s a cute story and you could tie lots of academics into it:
* riddles and adjectives…what’s the mystery machine?)
* calendar/seasons
* writing-list making
* friendship
